[0043] Example 1

[0044] According to the present invention, a real-time debugging method and system for the Yihui development environment based on a virtual simulation platform include: building a digital target prototype through a virtual simulation verification platform (iSystem) to replace real hardware, connecting with the development environment (RealEvo-IDE) of the Yihui operating system to achieve a one-click push debugging function, and a visual data generation interface provided by the virtual simulation verification platform to facilitate data generation and viewing test results, thereby achieving fast iteration from code writing to debugging to achieve the purpose of real-time debugging.

[0045] The real-time debugging method of the Yihui development environment based on the virtual simulation platform includes:

[0046] Step 1: Add an application in the RealEvo IDE.

[0047] In this embodiment, before the executable file generated by the application program is pushed to the digital target machine, the digital target machine is already running the RealEvo operating system. After that, the RealEvo operating system development environment (RealEvo-IDE) is successfully connected to the digital target machine, and after the executable file generated by the application program is pushed to the digital target machine, the digital target machine starts to execute the application program.

[0048] Step 2: Configure the simulation model in the virtual simulation verification platform (iSystem) and build a digital target prototype.

[0049] In this embodiment, the virtual simulation verification platform iSystem is a virtual development and verification platform. On the basis of maintaining high-speed cross-simulation of the complete system, it creatively introduces the idea of ​​graphical modeling into the construction of the virtual system, effectively solving the problems of high difficulty in building the virtual target system and poor scalability in existing virtual simulation products.

[0050] The virtual simulation verification platform iSystem includes multiple functional modules. One is the processor core, which is mainly responsible for the execution of the instruction set. Another is the IO device module, including on-chip peripherals, UART, network devices and other devices related to the processor address space. Another is the stub device used to expand functions. This device is inserted into the virtual system like a stub to expand and implement certain specific functions.

[0051] The configuration of the simulation model and the construction of the digital target prototype include: configuring the processor, SOC, board, and large system. The hierarchical relationship between iSystems is as follows: Figure 2 As shown; among which:

[0052] The processor core is mainly involved in the execution of instruction sets, processor event management, processor interrupt management, breakpoint management, watchpoint management, processor energy saving mode support, instruction set disassembly, memory management, IO management, general register management and other instruction-related functions. According to different instruction sets, it can be divided into ARM, PPC, SPARC, X86, 8051, DSP and other different cores for use.

[0053] The SOC model is based on a general-purpose processor core and adds on-chip peripherals according to different requirements. The purpose of implementing this model is to simulate the chip. This model generally cannot work independently.

[0054] The target system board model is based on the SOC model, plus user-defined on-board device modules.

[0055] The large system model is composed of multiple target board models. Its purpose is to simulate the user's complete system so that the user can complete system-level debugging and testing.

[0056] Step 3: Configure the network settings of the virtual simulation verification platform (iSystem) to ensure data transmission and status synchronization between the virtual simulation verification platform (iSystem) and the RealEvo operating system development environment (RealEvo-IDE).

[0057] Step 4: Configure the application in the RealEvo-IDE to ensure that it can successfully connect to the target digital prototype.

[0058] Step 5: After compiling the application in the RealEvo operating system development environment (RealEvo-IDE), push it to the target digital prototype with one click.

[0059] In this embodiment, the application is compiled and generated into a binary file which is pushed to the digital target prototype with one click.

[0060] Step 6: Debug the application in RealEvo-IDE.

[0061] In this embodiment, a virtual network card is used to manage data transmission and interaction between the virtual simulation platform and the Yihui development environment.

[0062] The present invention also provides a real-time debugging system for the Yihui development environment based on a virtual simulation platform. The real-time debugging system for the Yihui development environment based on the virtual simulation platform can be implemented by executing the process steps of the real-time debugging method for the Yihui development environment based on the virtual simulation platform, that is, technical personnel in this field can understand the real-time debugging method for the Yihui development environment based on the virtual simulation platform as the preferred implementation mode of the real-time debugging system for the Yihui development environment based on the virtual simulation platform.
