Description

Technical Field

[0001] This invention relates to the field of simulation control, and in particular to a simulation synchronization control method, apparatus, equipment, program product, and storage medium. Background Technology

[0002] When simulating electronic systems, a hybrid simulation platform consisting of multiple simulation modules may be used in some cases (for example, system-level simulation is performed using a first simulation tool while hardware and software co-simulation is performed using a second simulation tool). However, the simulation rates of the multiple simulation modules in the hybrid simulation platform may differ, so it is necessary to synchronize the multiple simulation modules in the hybrid simulation platform. However, there is a lack of a mature simulation synchronization control method in the relevant technologies, which may lead to poor simulation accuracy or low simulation efficiency.

[0003] Therefore, how to provide a solution to the above-mentioned technical problems is a problem that needs to be solved by those skilled in the art. Summary of the Invention

[0004] The purpose of this invention is to provide a simulation synchronization control method, device, equipment, program product, and storage medium. In this invention, the simulation scenario type of the current simulation stage of the hybrid simulation platform is first determined periodically. Then, the corresponding synchronization strategy is determined through a first correspondence relationship and sent as the target synchronization strategy to each simulation module so that any simulation module can synchronize with other simulation modules according to the target synchronization strategy. Based on this, the synchronization strategy applied by the hybrid simulation platform can be adapted to its current simulation stage, thereby improving simulation accuracy and efficiency.

[0005] To solve the above-mentioned technical problems, the present invention provides a simulation synchronization control method, comprising:

The hybrid simulation platform includes multiple simulation modules, which cooperate with each other to simulate the electronic system. The simulation scenario type is a predefined simulation scenario type that adapts to the corresponding synchronization strategy throughout the entire simulation process of the hybrid simulation platform.

[0007] Based on a preset first correspondence, a synchronization strategy corresponding to the target scene type is determined as the target synchronization strategy. The first correspondence includes the correspondence between simulation scene types and synchronization strategies.

[0008] The target synchronization strategy is sent to each simulation module in the hybrid simulation platform so that any simulation module can synchronize with other simulation modules according to the target synchronization strategy.

[0009] On the other hand, the periodic determination of the simulation scenario type to which the hybrid simulation platform belongs in the current simulation stage includes the following target scenario types:

[0010] Periodically acquire the preset type of status parameters of each simulation module in the hybrid simulation platform and the load status of the host machine of the hybrid simulation platform;

[0011] Based on the state parameters and the load state, the simulation scenario type of the current simulation stage of the hybrid simulation platform is determined as the target scenario type.

[0012] On the other hand, determining the simulation scenario type of the current simulation stage of the hybrid simulation platform based on the state parameters and the load state, including the target scenario type, includes:

[0029] On the other hand, the predefined simulation scenario types include low-interaction fault-tolerant scenarios, in which the number of data interactions between simulation modules is less than the preset standard.

[0030] Scene recognition conditions for low-interaction-tolerance scenarios include:

[0031] If the shared memory usage of each simulation module in the hybrid simulation platform is lower than the fifth preset threshold, it is identified as a low-interaction fault-tolerant scenario.

[0032] On the other hand, the periodic acquisition of preset type status parameters of each simulation module in the hybrid simulation platform and the load status of the host machine of the hybrid simulation platform includes:

[0033] Every preset period, it is determined whether a user-specified scenario type exists. The user-specified scenario type is the simulation scenario type received through the human-computer interaction device.

[0034] If a user-specified scene type exists, then the user-specified scene type will be used as the target scene type, and the currently existing user-specified scene type will be cleared.

[0035] If no user-specified scenario type exists, the system retrieves the status parameters of the preset types of each simulation module in the hybrid simulation platform, as well as the load status of the host machine of the hybrid simulation platform.

[0036] On the other hand, determining whether a user-specified scenario type exists at each preset period includes:

[0037] Every preset period, determine whether there is a simulation level received through the human-computer interaction device;

[0038] If it exists, the simulation scene type corresponding to the simulation level is determined according to the preset second correspondence, and is used as the user-specified scene type. The second correspondence is the correspondence between the simulation level and the simulation scene type.

[0039] If it does not exist, then it is determined that the user-specified scenario type does not exist.

[0040] The method of clearing the currently existing user-specified scenario type includes:

[0054] On the other hand, the hybrid simulation platform includes a first simulation module and a second simulation module. The first simulation module is a fast simulator, and the second simulation module is a system-level C language modeling library.

[0055] The simulation rate of the first simulation module includes the instruction execution rate, and the simulation rate of the second simulation module includes the clock frequency.

[0056] If the difference in simulation rate between various simulation modules in the hybrid simulation platform reaches a first preset threshold, then the scenario identified as simulation rate priority includes:

[0057] Determine whether the simulation rate ratio between the first simulation module and the second simulation module reaches a first preset threshold.

[0058] If this condition is met, it is identified as a simulation rate-priority scenario.

[0059] On the other hand, determining the simulation scenario type of the current simulation stage of the hybrid simulation platform based on the state parameters and the load state, including the target scenario type, includes:

[0060] Determine whether the simulation scenario type of the current simulation stage of the hybrid simulation platform can be determined based on the state parameters and the load state.

[0061] If possible, the simulation scenario type of the current simulation stage of the hybrid simulation platform, determined based on the state parameters and the load state, will be used as the target scenario type.

[0062] If not, the preset default simulation scene type will be used as the target scene type.

[0063] On the other hand, after sending the target synchronization strategy to each simulation module in the hybrid simulation platform, the simulation synchronization control method further includes:

[0067] If they are different, increment the cumulative number of strategy switching by one and determine whether the cumulative number of strategy switching has reached the sixth preset threshold.

[0068] If the goal is not achieved, the process ends.

[0069] If the target is reached, the cumulative number of strategy switching will be cleared to zero, and the following steps will be executed: the target synchronization strategy will be sent to each simulation module in the hybrid simulation platform.

Considering that different simulation stages in a hybrid simulation platform may be adapted to different synchronization strategies throughout the simulation process, by predefining multiple simulation scenario types and establishing a first correspondence between them and the synchronization strategies, the adapted synchronization strategies can be dynamically adjusted. Therefore, in this invention, the simulation scenario type to which the current simulation stage of the hybrid simulation platform belongs is first determined periodically, and then the corresponding synchronization strategy is determined through the first correspondence and sent to each simulation module as the target synchronization strategy, so that any simulation module can perform simulation synchronization with other simulation modules according to the target synchronization strategy. Based on this, the synchronization strategy applied by the hybrid simulation platform can be adapted to its current simulation stage, thereby improving simulation accuracy and simulation efficiency.

[0090] The core of this invention is to provide a simulation synchronization control method, device, equipment, program product, and storage medium. In this invention, the simulation scenario type of the current simulation stage of the hybrid simulation platform is first determined periodically. Then, the corresponding synchronization strategy is determined through a first correspondence and sent to each simulation module as the target synchronization strategy. This allows any simulation module to synchronize with other simulation modules according to the target synchronization strategy. Based on this, the synchronization strategy applied by the hybrid simulation platform can be adapted to its current simulation stage, thereby improving simulation accuracy and efficiency.

[0091] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0092] Please refer to Figure 1 , Figure 1 This is a flowchart illustrating the first simulation synchronization control method provided by the present invention, which includes:

[0093] S101: Periodically determine the simulation scenario type of the current simulation stage of the hybrid simulation platform as the target scenario type; the hybrid simulation platform includes multiple simulation modules, which cooperate with each other to simulate the electronic system. The simulation scenario type is: the predefined simulation scenario type that adapts to the corresponding synchronization strategy throughout the entire simulation process of the hybrid simulation platform.

[0094] Specifically, considering the technical problems mentioned above, and taking into account that "during the entire simulation process of a hybrid simulation platform, different simulation stages may be adapted to different synchronization strategies, so by predefining multiple simulation scene types and establishing a first correspondence with the synchronization strategy, the adapted synchronization strategy can be dynamically adjusted," this embodiment of the invention can predefine several simulation scene types according to the specific characteristics of each simulation stage in the hybrid simulation platform. Different simulation scene types are adapted to corresponding synchronization strategies, thereby making the synchronization strategy compatible with the current simulation scene type and avoiding affecting the efficiency or accuracy of the simulation.

[0095] Specifically, based on the above considerations, in this embodiment of the invention, the simulation scenario type to which the current simulation stage of the hybrid simulation platform belongs can be periodically determined as the target scenario type, so as to serve as the data basis for subsequent steps.

[0096] The electronic system simulated by the hybrid simulation platform can be of various types, such as a system-on-a-chip. The specific number of simulation modules in the hybrid simulation platform can be various, such as two or three, etc. The embodiments of the present invention do not limit this.

[0097] S102: Based on the preset first correspondence, determine the synchronization strategy corresponding to the target scene type as the target synchronization strategy. The first correspondence includes the correspondence between the simulation scene type and the synchronization strategy.

[0098] Specifically, after obtaining the target scene type, in order to improve the efficiency and accuracy of determining the synchronization strategy, the present invention pre-sets a first correspondence relationship. Therefore, in this step, the synchronization strategy corresponding to the target scene type can be determined according to the pre-set first correspondence relationship, which serves as the target synchronization strategy.

[0099] S103: Send the target synchronization strategy to each simulation module in the hybrid simulation platform so that any simulation module can synchronize with other simulation modules according to the target synchronization strategy.

[0100] Specifically, after determining the target synchronization strategy that is currently compatible with the hybrid simulation platform, the target synchronization strategy can be sent to each simulation module in the hybrid simulation platform so that any simulation module can synchronize with other simulation modules according to the target synchronization strategy.

[0101] Specifically, for a better explanation of the embodiments of the present invention, please refer to... Figure 2 , Figure 2 This is a schematic diagram illustrating the relationship between a synchronous control module and a hybrid simulation platform provided by the present invention. Figure 2 The synchronization control module is used to execute the steps of the simulation synchronization control method in this embodiment of the invention. The synchronization control module can interact with various simulation modules in the hybrid simulation platform (e.g., including the first simulation module and the second simulation module) simultaneously. For example, the hybrid simulation platform includes QEMU (Quick Emulator) and SystemC (SystemC, a system-level C language modeling library). Every 100ms is a cycle, the current scenario type is determined to be "simulation rate priority scenario"; according to the preset first correspondence (simulation rate priority scenario corresponds to time window synchronization strategy), the strategy is sent to QEMU and SystemC, and the two perform simulation synchronization according to the time window synchronization strategy (e.g., synchronization state after independent operation within every 1ms window).

[0102] This invention provides a simulation synchronization control method. Considering that different simulation stages in a hybrid simulation platform may be adapted to different synchronization strategies throughout the simulation process, by predefining multiple simulation scenario types and establishing a first correspondence between them and the synchronization strategies, the adapted synchronization strategies can be dynamically adjusted. Therefore, this invention first periodically determines the simulation scenario type to which the current simulation stage of the hybrid simulation platform belongs, and then determines the corresponding synchronization strategy through the first correspondence. This strategy is then sent to each simulation module as the target synchronization strategy, so that any simulation module can synchronize with other simulation modules according to the target synchronization strategy. Based on this, the synchronization strategy applied by the hybrid simulation platform can be adapted to its current simulation stage, thereby improving simulation accuracy and efficiency.

[0103] Based on the above embodiments:

[0104] As an optional implementation, the simulation scenario type of the current simulation stage of the hybrid simulation platform is periodically determined, and the target scenario type includes:

[0105] Periodically acquire the preset type of status parameters of each simulation module in the hybrid simulation platform and the load status of the host machine of the hybrid simulation platform;

[0106] Based on the state parameters and load status, the simulation scenario type of the current simulation stage of the hybrid simulation platform is determined and used as the target scenario type.

[0107] Specifically, for a better explanation of the embodiments of the present invention, please refer to... Figure 3 , Figure 3 This is a schematic diagram illustrating the relationship between another synchronization control module and a hybrid simulation platform provided by the present invention. Figure 3 The synchronization control module mainly includes a simulation monitoring submodule (used to periodically acquire the preset type status parameters of each simulation module in the hybrid simulation platform, the load status of the host machine of the hybrid simulation platform, and user input), a synchronization strategy control submodule (used to determine the simulation scenario type of the current simulation stage of the hybrid simulation platform based on user input, status parameters, and load status, as the target scenario type), and a synchronization strategy output notification submodule (used to receive the target scenario type and send the target scenario type to each simulation module).

[0108] Specifically, considering that the operating status of the simulation module (such as speed and interaction frequency) and the host machine load (such as CPU usage) directly reflect the characteristics of the current simulation stage and are the core basis for identifying the simulation scenario type, this embodiment of the invention periodically collects these data to capture scenario changes in real time, providing support for strategy adjustments.

[0109] Specifically, for example, every 50ms, the following parameters are collected: QEMU instruction execution rate (MIPS, Million Instructions Per Second) is 2000 MIPS, SystemC clock frequency (clock cycles / second) is 2M clock cycles / second, host CPU (Central Processing Unit) load rate is 85%, and shared memory usage rate is 70%. Based on these parameters, the current scenario type is determined to be "simulation rate priority scenario".

[0110] Of course, in addition to this specific form, "periodically determining the simulation scene type to which the current simulation stage of the hybrid simulation platform belongs, as the target scene type" can also be in other specific forms, and this embodiment of the invention does not limit it here.

[0111] As an optional implementation, based on state parameters and load status, the simulation scenario type of the current simulation stage of the hybrid simulation platform is determined. The target scenario types include:

[0112] Determine whether the status parameters and load status meet the scene recognition conditions for any predefined simulation scene type;

[0113] If the conditions are met, the simulation scenario type that satisfies the scenario recognition conditions in terms of state parameters and load state will be taken as the target scenario type.

[0114] Specifically, considering that different scene types have quantifiable characteristics (such as high interaction frequency corresponding to high accuracy priority scenes), by pre-setting scene recognition conditions, the parameters collected in real time can be compared with the conditions to achieve accurate determination of scene type. Therefore, the scheme in the embodiments of the present invention was designed.

[0115] For example, the predefined identification condition for "simulation accuracy priority scenario" is "interaction event trigger frequency ≥ 1,000,000 times / ms". If the collected interaction event trigger frequency (such as interrupt / ms) between QEMU and SystemC is 1,200,000 times / ms, this condition is met, and the current scenario is determined to be simulation accuracy priority scenario.

[0116] Of course, in addition to this specific form, "determining the simulation scenario type of the current simulation stage of the hybrid simulation platform based on the state parameters and load status, and using it as the target scenario type" can also be in other specific forms, and this embodiment of the invention does not limit it here.

[0117] As an optional implementation, the predefined simulation scenario types include simulation rate-priority scenarios;

[0118] The scene recognition conditions for the simulated rate-first scenario include:

[0119] If the difference in simulation rate between various simulation modules in the hybrid simulation platform reaches the first preset threshold, it is identified as a simulation rate priority scenario.

[0120] Preset state parameters include simulation rate.

[0121] Specifically, considering that when the speed difference between simulation modules is too large (such as QEMU being much faster than SystemC), the synchronization overhead will significantly affect the simulation efficiency. In this case, the speed needs to be prioritized. Therefore, a "simulation speed priority scenario" is defined, and the speed difference is used as the core identification condition.

[0122] Specifically, for example, the first preset threshold is 1000. In the hybrid simulation platform, the instruction execution rate of QEMU is 5000 MIPS, and the clock frequency of SystemC is 5 MHz clock cycles / second. The ratio of their rates is 1000 (reaching the threshold), which is identified as a simulation rate priority scenario.

[0123] As an optional embodiment, the scene recognition conditions for simulating rate-priority scenarios also include:

[0124] If the load rate of the host machine's central processing unit reaches the second preset threshold, it is identified as a simulation rate priority scenario.

[0125] The host machine's load status includes the CPU load rate.

[0126] Specifically, considering that the system's processing capacity is limited when the host CPU load is too high, continuing to use a high-precision synchronization strategy would exacerbate the load and cause simulation stuttering. Therefore, CPU load rate is used as a supplementary identification condition for simulation rate-priority scenarios to prioritize ensuring operational efficiency.

[0127] For example, the second preset threshold is 90%. The host CPU load rate is 92%. Although the rate difference between QEMU and SystemC does not reach the first threshold, it still meets the identification conditions for the simulation rate priority scenario and is determined to be this scenario.

[0128] As an optional embodiment, the scene recognition conditions for simulating rate-priority scenarios also include:

[0129] If the shared memory usage of each simulation module in the hybrid simulation platform reaches the third preset threshold, it is identified as a simulation rate priority scenario, and the shared memory is used to cache the interactive data between simulation modules.

[0130] The default status parameters include the shared memory usage rate.

[0131] Specifically, considering that a high shared memory (used for data interaction caching between modules) occupancy rate indicates frequent data interaction between modules and high synchronization overhead, it is necessary to prioritize speed to reduce blocking. Therefore, the shared memory occupancy rate is used as a supplementary identification condition for simulating speed-priority scenarios.

[0132] Specifically, for example, the third preset threshold is 90%. In the hybrid simulation platform, the shared memory occupancy rate is 91%. Even if the CPU load rate and speed difference do not meet the standard, it still meets the identification conditions of the simulation speed priority scenario and is judged as such.

[0133] As an optional implementation, the predefined simulation scenario types include simulation accuracy-priority scenarios;

[0134] Scene recognition conditions for simulation accuracy-priority scenarios include:

[0135] If the frequency of interaction events between various simulation modules reaches the fourth preset threshold, it is identified as a simulation accuracy priority scenario.

[0136] The preset type of status parameters includes the frequency of interactive event triggering.

[0137] Specifically, considering that when there are frequent interaction events between modules (such as high-frequency interrupts), timing consistency is crucial to simulation accuracy. If synchronization is not timely, it will lead to data inconsistency. Therefore, a "simulation accuracy priority scenario" is defined, and the frequency of interaction event triggering is used as the core identification condition.

[0138] For example, the fourth preset threshold is 1,000,000 times / ms. The trigger frequency of QEMU and SystemC interaction events (such as interrupts and data transmissions) is 1,500,000 times / ms, which meets the conditions and is determined to be a simulation accuracy priority scenario.

[0139] As an optional implementation, the predefined simulation scenario types include low-interaction fault-tolerant scenarios, in which the number of data interactions between simulation modules is less than a preset standard;

[0140] Scene recognition conditions for low-interaction-tolerance scenarios include:

[0141] If the shared memory usage of each simulation module in the hybrid simulation platform is lower than the fifth preset threshold, it is identified as a low-interaction fault-tolerant scenario.

[0142] Specifically, considering that a low shared memory usage rate between simulation modules indicates less data interaction and higher fault tolerance, a more flexible synchronization strategy (such as an optimistic synchronization strategy) can be adopted to reduce overhead, a "low interaction fault tolerance scenario" is defined, and the shared memory usage rate is used as the identification condition.

[0143] Specifically, for example, the fifth preset threshold is 5%. In the hybrid simulation platform, the shared memory usage rate is 3% (below the threshold), which is judged as a low interaction fault tolerance scenario.

[0144] Of course, in addition to the various specific scenario types mentioned above, simulation scenario types may also include other types, which are not limited in this embodiment of the invention.

[0145] As an optional embodiment, periodically acquiring the preset type of status parameters of each simulation module in the hybrid simulation platform and the load status of the host machine of the hybrid simulation platform includes:

[0146] Every preset period, it is determined whether a user-specified scenario type exists. The user-specified scenario type is the simulation scenario type received through the human-computer interaction device.

[0147] If a user-specified scene type exists, then the user-specified scene type will be used as the target scene type, and the currently existing user-specified scene type will be cleared.

[0148] If no user-specified scenario type exists, the system retrieves the status parameters of the preset types of each simulation module in the hybrid simulation platform, as well as the load status of the host machine of the hybrid simulation platform.

[0149] Specifically, considering that users may manually specify the scene type according to the simulation target (such as the need for high precision in a specific stage), user intervention can be supported; at the same time, in order to avoid the user's specification being effective for a long time and affecting dynamic adjustment, the specification needs to be cleared after use, so the solution in the embodiment of the present invention is designed.

[0150] For example, if the preset period is 100ms, and it is detected that the user has specified "simulation accuracy priority scenario" through the human-computer interaction device, then it will be used as the target scenario type, and this specification will be cleared after the period ends. In the next period, it will be re-evaluated to see if there is a new user specification.

[0151] As an optional implementation, determining whether a user-specified scenario type exists at preset intervals includes:

[0152] Every preset period, determine whether there is a simulation level received through the human-computer interaction device;

[0153] If it exists, the simulation scene type corresponding to the simulation level is determined according to the preset second correspondence, which is used as the user-specified scene type. The second correspondence is the correspondence between the simulation level and the simulation scene type.

[0154] If it does not exist, then it is determined that the user-specified scenario type does not exist.

[0155] Clearing currently existing user-specified scenario types includes:

[0156] Clear the currently existing simulation level.

[0157] Specifically, considering that users may be more accustomed to expressing their needs through "simulation level" (such as instruction level, periodic precision level) rather than directly specifying the scene type, the solution in this embodiment of the invention is designed to simplify user operations and achieve indirect specification of scene types by establishing a correspondence between levels and scenes.

[0158] Specifically, for example, if the user inputs "instruction level" simulation level, the target scenario type is determined to be simulation rate priority scenario based on the second correspondence (instruction level corresponds to simulation rate priority scenario); when clearing the user-specified simulation level, the "instruction level" simulation level input is directly cleared.

[0159] As an optional implementation, simulation levels include instruction level, cycle-accurate level, and preset additional levels;

[0160] Simulation scenario types include simulation rate-priority scenarios, simulation accuracy-priority scenarios, and low-interaction fault-tolerant scenarios;

[0161] The second correspondence includes:

[0162] The instruction level corresponds to the simulation rate-priority scenario;

[0163] The periodic accuracy level corresponds to simulation scenarios where precision is prioritized.

[0164] Additional levels correspond to scenarios with low interaction tolerance.

[0165] Specifically, considering that different simulation levels correspond to different core requirements (such as instruction-level focusing on speed and cycle-precision-level focusing on accuracy), clarifying the correspondence between the two can achieve accurate mapping of user needs to scenario types and improve strategy matching efficiency. Therefore, the solution in the embodiments of this invention was designed.

[0166] For example, simulation levels include IA (Instruction Accuracy), CCA (Cycle-Cycle Accuracy), and additional levels; scenario types include simulation rate-priority scenarios, simulation accuracy-priority scenarios, and low-interaction fault-tolerant scenarios. IA corresponds to simulation rate-priority scenarios, CCA corresponds to simulation accuracy-priority scenarios, and additional levels correspond to low-interaction fault-tolerant scenarios. When a user selects CCA, the target scenario type is simulation accuracy-priority scenario.

[0167] As an optional implementation, the simulation scenario types include simulation rate-priority scenarios, simulation accuracy-priority scenarios, and low-interaction fault-tolerant scenarios;

[0168] Synchronization strategies include time window synchronization strategy, event-driven synchronization strategy, and optimistic synchronization strategy;

[0169] The first correspondence includes:

[0170] Simulation rate-priority scenario corresponding to time window synchronization strategy;

[0171] Event-driven synchronization strategy corresponding to simulation accuracy-priority scenarios;

[0172] Optimistic synchronization strategies are appropriate for scenarios with low interaction tolerance.

[0173] Specifically, considering that different simulation scenario types have different synchronization requirements (such as rate priority requiring efficient synchronization, and accuracy priority requiring strict timing), the optimal strategy is matched for each scenario to ensure that the synchronization effect is consistent with the scenario requirements and improve the overall simulation performance. Therefore, the scheme in the embodiments of the present invention was designed.

[0174] Specifically, simulation scenario types include simulation rate-first scenarios, simulation accuracy-first scenarios, and low-interaction fault-tolerant scenarios; synchronization strategies include time-window synchronization strategies, event-driven synchronization strategies, and optimistic synchronization strategies. The correspondence is as follows: simulation rate-first scenarios correspond to time-window synchronization strategies, simulation accuracy-first scenarios correspond to event-driven synchronization strategies, and low-interaction fault-tolerant scenarios correspond to optimistic synchronization strategies. When the target scenario is a low-interaction fault-tolerant scenario, the optimistic synchronization strategy is matched.

[0175] As an optional embodiment, the hybrid simulation platform includes a first simulation module and a second simulation module, wherein the first simulation module is a fast simulator and the second simulation module is a system-level C language modeling library;

[0176] The simulation rate of the first simulation module includes the instruction execution rate, and the simulation rate of the second simulation module includes the clock frequency.

[0177] If the difference in simulation rate between various simulation modules in the hybrid simulation platform reaches a first preset threshold, then the scenario identified as simulation rate priority includes:

[0178] Determine whether the simulation rate ratio between the first simulation module and the second simulation module reaches a first preset threshold.

[0179] If this condition is met, it is identified as a simulation rate-priority scenario.

[0180] Specifically, considering that the speed metrics (instruction execution speed and clock frequency) of fast simulators (such as QEMU) and system-level modeling libraries (such as SystemC) are different in a hybrid simulation platform, the difference can be quantified by the ratio of their speeds, and the scenarios that need to prioritize speed can be accurately identified. Therefore, the solution in the embodiments of this invention was designed.

[0181] For example, the hybrid simulation platform includes a first simulation module QEMU and a second simulation module SystemC. The simulation rate of QEMU is the instruction execution rate (3000 MIPS), and the simulation rate of SystemC is the clock frequency (3M clock cycles / second). The ratio of the two is 1000 (reaching a first preset threshold), which is identified as a simulation rate priority scenario.

[0182] As an optional implementation, based on state parameters and load status, the simulation scenario type of the current simulation stage of the hybrid simulation platform is determined. The target scenario types include:

[0183] Based on the state parameters and load status, determine whether the simulation scenario type of the current simulation stage of the hybrid simulation platform can be identified.

[0184] If possible, the simulation scenario type of the current simulation stage of the hybrid simulation platform, determined based on the state parameters and load status, will be used as the target scenario type.

[0185] If not, the preset default simulation scene type will be used as the target scene type.

[0186] Specifically, for a better explanation of the embodiments of the present invention, please refer to... Figure 4 , Figure 4 This is a flowchart illustrating the second simulation synchronization control method provided by the present invention. After the process begins, the state parameters of the simulation module and the load state of the host machine are first parsed. Then, it is determined whether it is a simulation rate-priority scenario. If so, a time window synchronization strategy is adopted. If not, it is determined whether it is a simulation accuracy-priority scenario. If so, an event-driven synchronization strategy is adopted. If not, it is determined whether it is a low-interaction fault-tolerant scenario. If so, an optimistic synchronization strategy is adopted. If none of these apply, the preset default simulation scenario type is used as the target scenario type. Finally, the target scenario type is sent to each simulation module, and the process ends.

[0187] Specifically, considering that when the parameters collected in real time do not meet the recognition conditions of any predefined scene, the default scene type can be used to ensure that the synchronization strategy is not missing, avoid interruption in the simulation process, and ensure system stability. Therefore, the scheme in the embodiment of the present invention was designed.

[0188] Specifically, if the collected state parameters (rate difference 800, CPU load rate 70%, shared memory usage rate 60%, interaction frequency 500,000 times / ms) do not meet the conditions for simulation rate priority, accuracy priority, and low interaction fault tolerance scenario, then the default scenario type can be simulation accuracy priority scenario.

[0189] Of course, in addition to this specific form, "determining the simulation scenario type of the current simulation stage of the hybrid simulation platform based on the state parameters and load status, and using it as the target scenario type" can also be achieved in other forms, and this embodiment of the invention does not limit it here.

[0190] As an optional embodiment, after the target synchronization strategy is sent to each simulation module in the hybrid simulation platform, the simulation synchronization control method further includes:

[0191] The control prompt indicates the current target scenario type and target synchronization strategy of the hybrid simulation platform.

[0192] Specifically, considering that users can monitor the simulation process or manually intervene (such as adjusting parameters) if they can understand the simulation status in real time (such as the current strategy), the prompt function can provide feedback on key information to improve user controllability.

[0193] For example, after the event-driven synchronization strategy is sent to each simulation module, the prompt (such as the display screen) shows "Current target scenario type: simulation accuracy priority scenario, target synchronization strategy: event-driven synchronization strategy".

[0194] As an optional embodiment, after determining a synchronization strategy corresponding to the target scene type based on a preset first correspondence, and before sending the target synchronization strategy to each simulation module in the hybrid simulation platform, the simulation synchronization control method further includes:

[0195] Determine whether the target synchronization strategy determined in this cycle is the same as the target synchronization strategy determined in the previous cycle;

[0196] If they are different, increment the cumulative number of strategy switching by one and determine whether the cumulative number of strategy switching has reached the sixth preset threshold.

[0197] If the goal is not achieved, the process ends.

[0198] If the target is reached, the cumulative number of strategy switching will be cleared to zero, and the following steps will be executed: the target synchronization strategy will be sent to each simulation module in the hybrid simulation platform.

[0199] Specifically, for a better explanation of the embodiments of the present invention, please refer to... Figure 5 , Figure 5 This is a flowchart illustrating a strategy debouncing function provided by the present invention. The process begins by determining whether the target synchronization strategy for the current cycle differs from the previous cycle; if not, it ends directly. If so, the cumulative strategy switching count is incremented by 1. Next, it determines whether the cumulative strategy switching count has reached a sixth preset threshold; if not, it ends. If so, the target synchronization strategy is output, the cumulative strategy switching count is set to 0, and finally, the process ends.

[0200] Specifically, considering that frequent switching of synchronization strategies within a short period of time can cause system oscillations (such as the simulation module repeatedly adjusting synchronization logic), affecting simulation stability, this embodiment of the invention avoids frequent switching and achieves anti-jitter by accumulating the number of switching attempts and setting a threshold.

[0201] Specifically, for example, the sixth preset threshold is 3. If the target synchronization strategy (time window synchronization) of this period is different from that of the previous period (event-driven synchronization), the cumulative number of strategy switching is 2 (not reaching 3), and no new target synchronization strategy is sent; if the target synchronization strategy of the next period is still different, and the cumulative number reaches 3, a new target synchronization strategy is sent and the cumulative number of strategy switching is cleared to zero.
