Description

Technical Field

[0001] This invention relates to the field of high-speed digital signal transmission technology, and more specifically, to a method, system, and electronic device for optimizing synchronous data crosstalk effects. Background Technology

[0002] Synchronous high-speed digital signals are widely used in modern digital signal systems, such as high-speed interfaces and communication systems. Figure 1 This is a schematic diagram of a high-speed parallel digital signal system. (Example:) Figure 1 As shown, module A and module B transmit parallel digital signals through several parallel channels. The parallel path (i.e., parallel channel) can be designed as a passive metal trace or as a signal path that includes an intermediate buffer.

[0003] With advancements in chip manufacturing processes, integrated circuits can process digital signals at increasingly faster speeds. Furthermore, these advancements lead to higher integration levels and smaller overall dimensions. In addition, the voltage VDD used by the entire system is being designed to be smaller to improve power consumption.

[0004] However, while people enjoy the technological benefits of increased data throughput and enhanced data processing capabilities, engineers need to solve the increasingly severe problem of crosstalk in high-speed digital signals. Specifically, on the one hand, changes in data rate make the unit interval (UI) shorter and shorter, causing the robustness of crosstalk signals to continuously decrease; on the other hand, the continuously decreasing voltage VDD also leads to more severe clock data jitter.

[0005] When the high-speed parallel digital signal is synchronous data, such as Figure 2 As shown, since each channel is triggered by the clock of the same clock domain, the transition edges of the data in each channel are aligned. When there is crosstalk between channels, the crosstalk signal of the initiator (crosstalk initiating channel) will be coupled to the transition edge of the victim (crosstalk receiving channel). The susceptibility of the transition edge to interference will worsen its own data jitter.

[0006] For example, when channels A and B are used to transmit parallel synchronous digital signals, and there is crosstalk between channels A and B; if at a certain transition edge, the data in channel B remains unchanged, then the transition edge in channel A remains unchanged; if the data in channel B transitions in the same direction as the transition in channel A, then the transition speed of A increases, and the timing of the transition edge becomes earlier; if the data in channel B transitions in the opposite direction to the transition in channel A, then the transition speed of A decreases, and the timing of the transition edge becomes later. Therefore, if... Figure 3As shown, when two channels transmit different data codes, crosstalk between them will cause the data jitter of the received signal to deteriorate, resulting in bit errors.

[0007] There are two existing solutions to crosstalk problems (not limited to synchronous data). The first is a passive solution, the core of which is to "minimize the impact of crosstalk." For example, increasing the distance between crosstalking paths reduces the coupling capacitance between them, thereby reducing or even eliminating crosstalk; or adding shielding lines between crosstalking paths reduces the direct impact between them, thereby reducing or even eliminating crosstalk. The other is an active solution, the core of which is not to seek to reduce crosstalk itself, but to positively compensate the victim path. For example, if the coupling of the insulator path to the victim path is +X, then a reverse coupling of -X can be artificially created and superimposed on the victim path to achieve compensation for the victim path.

[0008] However, for existing passive solutions, both increasing the distance and adding shielding are affected by physical space layout, making them difficult to fully implement. For example, increasing the distance is usually used to slightly reduce crosstalk, but since the space for high-speed parallel lines in the system is limited, it is impossible to extend the distance to infinity, and a large amount of crosstalk remains. The shielding solution also requires a trade-off between parasitic capacitance and physical layout space, making it difficult to completely eliminate crosstalk. In existing active solutions, for the victim path, although the compensation circuit applies an influence of -X to cancel out the crosstalk signal itself, the victim path now has additional parasitic capacitance from the compensation circuit on top of the original circuit, affecting the bandwidth of high-speed signals. In addition, for the victim path, a module with a drive capability of -X needs to be built, which itself increases power consumption and chip area significantly. Thirdly, in order to accurately quantify the required drive capability X, high-performance active compensation solutions also require a corresponding crosstalk detection module, which further increases design complexity.

[0009] As can be seen from the two existing solutions mentioned above, there is an urgent need for a solution that can be designed simply and effectively reduce crosstalk effects between digital signal paths. Summary of the Invention

[0010] In view of the above problems, the purpose of this invention is to provide a synchronous data crosstalk effect optimization system to solve the problems of high complexity and poor optimization effect of existing synchronous data crosstalk effect optimization schemes.

[0011] The method for optimizing synchronous data crosstalk effects provided by this invention includes:

[0012] The jump edge jitter range of the victim channel and the jump edge jitter range of the attacker channel were measured separately.

[0013] Choose either the victim channel or the perpetrator channel, add a first delay module to the sending end of the selected channel, and add a second delay module to the end of the other unselected channel;

[0014] The first delay module and the second delay module are configured based on the jitter range of the transition edge of the victim channel and the jitter range of the transition edge of the attacker channel;

[0015] Based on the configured first delay module and second delay module, crosstalk effect optimization is performed on the digital data in the victim channel and the digital data in the attacker channel.

[0016] In addition, an alternative approach is to optimize the crosstalk effect of the digital data in the victim channel and the digital data in the perpetrator channel based on the configured first delay module and second delay module, including:

[0017] The digital signal in the selected channel is delayed based on the configured first delay module so that the transition edges of the digital signal in the selected channel and the digital signal in the unselected channel are staggered; and the digital signal in the unselected channel is delayed based on the configured second delay module so that the transition edges of the digital signal in the selected channel and the digital signal in the unselected channel are restored to alignment.

[0018] Alternatively, the transition edge jitter range may include the transition edge rise time and the transition edge jitter time.

[0019] Alternatively, the delay values ​​of the first delay module and the second delay module can be equal.

[0020] Alternatively, during the configuration of the first delay module and the second delay module based on the jitter range of the transition edge of the victim channel and the jitter range of the transition edge of the attacker channel:

[0021] The delay value is set such that the jitter range of the victim channel and the jitter range of the attacker channel do not overlap at all.

[0022] Alternatively, an optional approach is to define the jitter range of the victim channel as F1, the jitter range of the attacker channel as F2, and the delay value as D. Then, during the configuration of the first delay module and the second delay module based on the jitter ranges of the victim channel and the attacker channel, the delay value satisfies the following constraint:

[0023] Where N is a non-negative integer and UI is the unit interval.

[0024] Alternatively, N=0; and F1 and F2 can both be obtained through simulation or testing.

[0025] On the other hand, the present invention also provides a synchronous data crosstalk effect optimization system, including a jitter measurement unit, a delay module setting unit, a delay module configuration unit, and a signal processing unit; wherein, the jitter measurement unit is used to measure the jitter range of the jump edge of the victim channel and the jitter range of the jump edge of the attacker channel respectively.

[0026] The delay module setting unit is used to select one of the victim channel and the perpetrator channel, add a first delay module at the sending end of the selected channel, and add a second delay module at the end of the other unselected channel;

[0027] The delay module configuration unit is used to configure the first delay module and the second delay module based on the jitter range of the jump edge of the victim channel and the jitter range of the jump edge of the attacker channel;

[0028] The signal processing unit is configured to delay the digital signal in the selected channel based on the configured first delay module, so that the transition edges of the digital signal in the selected channel and the digital signal in the unselected channel are staggered; and to delay the digital signal in the unselected channel based on the configured second delay module, so that the transition edges of the digital signal in the selected channel and the digital signal in the unselected channel are restored to alignment.

[0029] Furthermore, the present invention also provides an electronic device, comprising: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the steps of the aforementioned method for optimizing the synchronous data crosstalk effect.

[0030] Furthermore, the present invention also provides a computer-readable storage medium storing instructions that, when executed on an electronic device, cause the electronic device to perform the aforementioned method for optimizing synchronous data crosstalk effects.

[0031] Furthermore, the present invention also provides a synchronous digital signal system, including at least two parallel channels, wherein the crosstalk effect of any two parallel channels is optimized based on the aforementioned synchronous data crosstalk effect optimization method.

[0032] Compared with the prior art, the synchronous data crosstalk effect optimization method, system, and electronic device provided by the present invention have the following advantages:

[0033] The synchronous data crosstalk effect optimization method provided by this invention is essentially a passive solution. Compared with previous active compensation methods, this solution significantly reduces implementation difficulty, power consumption, and area overhead, thus substantially lowering costs. Compared to conventional passive solutions, this solution can optimize crosstalk effects for high-speed synchronous digital signals with very small space overhead (delay modules are typically small in area), and can almost completely eliminate the impact of crosstalk on jitter.

[0047] Various modifications and variations can be made to the specific embodiments described in this specification without departing from the scope or spirit of the invention, as will be apparent to those skilled in the art. Other embodiments derived from this specification will also be readily apparent to those skilled in the art. This application specification and embodiments are merely exemplary.

[0048] The following details the specific process of the synchronous data crosstalk effect optimization method provided by this invention.

[0049] Figure 4This is a schematic diagram of a model for optimizing the synchronous data crosstalk effect according to an embodiment of the present invention. Figure 5 This is a flowchart of the synchronous data crosstalk effect optimization method provided according to an embodiment of the present invention, combined with... Figure 4 and Figure 5 It can be seen that the synchronous data crosstalk effect optimization method provided by the present invention includes:

[0050] S110: Measure the jitter range of the jump edge in the victim channel and the jitter range of the jump edge in the attacker channel, respectively.

[0051] Specifically, for both the victim channel and the perpetrator channel, the transition edge jitter range includes the transition edge rise time and the transition edge jitter time. The sum of the transition edge rise time and the transition edge jitter time is the value of the transition edge jitter range.

[0052] S120: Select one of the victim channel and the perpetrator channel, add a first delay module to the sending end of the selected channel; and add a second delay module to the end of the other unselected channel.

[0053] It should be noted that by adding a delay module at the transmitting end (after) of one of the victim channel and the perpetrator channel, the transition edges of the internal signals of the two channels can be directly staggered at the initial position of the channel (near the transmitting end), thereby eliminating the influence of crosstalk signals on the transition edges and effectively avoiding the deterioration of jitter. At the same time, in order to ensure that the receiving end can still receive the two synchronized signals correctly, a delay module of the same size needs to be added at the end of the other channel so that the transition edges of the internal signals of the two channels are aligned before entering the receiving end, ensuring that the receiving end receives the correct signal.

[0054] S130: Configure the first delay module and the second delay module based on the jitter range of the transition edge of the victim channel and the jitter range of the transition edge of the attacker channel.

[0055] Specifically, in order to ensure that the transition edges of the signals ultimately input to the receiver from the two channels (the attacker channel and the victim channel) are aligned and synchronized, the delay values ​​of the first delay module of the selected channel and the second delay module of the unselected channel need to be equal.

[0056] Furthermore, to ensure that the two signals do not crosstalk each other at the transition edge position, during the configuration of the first delay module and the second delay module based on the transition edge jitter range of the victim channel and the transition edge jitter range of the exertor channel:

[0057] The delay value is set such that the jitter range of the victim channel and the jitter range of the attacker channel do not overlap at all.

[0058] In the actual design process, assuming the jitter range of the victim channel's transition edge is F1, the jitter range of the attacker channel's transition edge is F2, and the delay value is D; then, in the process of configuring the first delay module and the second delay module based on the jitter ranges of the victim channel and the attacker channel's transition edge, the delay value satisfies the following constraint:

[0059] Where N is a non-negative integer, and UI is the built-in unit interval of the delay module.

[0060] It should be noted that, considering system overhead and performance optimization, N should be as small as possible, with 0 being the optimal value. In addition, to obtain the jitter range of the victim channel and the jitter range of the attacker channel, the jitter range of the victim channel and the jitter range of the attacker channel can be obtained through simulation or testing.

[0061] S140: Based on the configured first delay module and second delay module, perform crosstalk effect optimization on the digital data in the victim channel and the digital data in the attacker channel (both are synchronous data).

[0062] Specifically, the process of optimizing the crosstalk effect of the synchronized data of the two channels based on the configured first delay module and the second delay module includes: delaying the digital signal in the selected channel based on the configured first delay module so that the transition edges of the digital signal in the selected channel and the digital signal in the unselected channel are staggered; and delaying the digital signal in the unselected channel based on the configured second delay module so that the transition edges of the digital signal in the selected channel and the digital signal in the unselected channel are restored to alignment.

[0063] It should be noted that the synchronous data crosstalk effect optimization method provided by this invention is explained using a pair of channels as an example. Since the impact and analysis of crosstalk are performed in pairs, combining "perpetrator and victim," in practical applications, for multi-channel parallel circuits, the synchronous data crosstalk effect optimization method provided by this invention can be used to optimize each channel in pairs. For example, the synchronous data crosstalk effect optimization method provided by this invention is applied to synchronous digital signal systems, which include multiple (at least two) parallel channels. Any two parallel channels in the synchronous digital signal system can have their crosstalk effects optimized using the synchronous data crosstalk effect optimization method provided by this invention.

[0064] The synchronous data crosstalk effect optimization method provided by this invention uses a delay module added to the transmission path to create a skew (delay difference) between the path signals, so that the crosstalk effect avoids the transition edge, thereby eliminating the deterioration of the transition edge jitter by the crosstalk signal. At the same time, the same delay module is used before the receiving end to restore the synchronization of the synchronization signal, ensuring the timing requirements of the receiving end.

[0065] Figure 6 This is a block diagram of the synchronous data crosstalk effect optimization system of the present invention. The synchronous data crosstalk effect optimization system 400 provided by the present invention is based on a synchronous data crosstalk effect optimization method and can be installed in electronic devices. Depending on the functions implemented, such as... Figure 6 As shown, the synchronous data crosstalk effect optimization system 400 may include: a jitter measurement unit 410, a delay module setting unit 420, a delay module configuration unit 430, and a signal processing unit 440. The unit described in this invention can also be called a module, which mainly refers to a series of computer program segments that can be executed by the processor of an electronic device and can perform a fixed function, and are stored in the memory of the electronic device.

[0066] In this embodiment, the functions of each module / unit are as follows:

[0067] The jitter measurement unit 410 is used to measure the jitter range along the transition edge of the victim channel and the jitter range along the transition edge of the attacker channel, respectively.

[0068] The delay module setting unit 420 is used to select one of the victim channel and the perpetrator channel, add a first delay module at the sending end of the selected channel, and add a second delay module at the end of the other unselected channel;

[0069] The delay module configuration unit 430 is used to configure the first delay module and the second delay module based on the jitter range of the jump edge of the victim channel and the jitter range of the jump edge of the attacker channel;

[0070] The signal processing unit 440 is configured to perform delay processing on the digital signal in the selected channel based on the configured first delay module, so that the transition edges of the digital signal in the selected channel and the digital signal in the unselected channel are staggered; and to perform delay processing on the digital signal in the unselected channel based on the configured second delay module, so that the transition edges of the digital signal in the selected channel and the digital signal in the unselected channel are restored to alignment.
