[0080] It should be noted that all the expressions using "first" and "second" in the embodiments of the present invention are used to distinguish two entities or parameters with the same name but different ones. It can be seen that "first" and "second" are only for the convenience of expression and should not be construed as a limitation on the embodiments of the present invention. This will not be repeated in the subsequent embodiments.
[0081] According to one aspect of the present invention, an embodiment of the present invention provides a method for generating a control signal, as Figure 1 shown, which may include the steps:
[0082] S1. Receive multiple timing probabilities and value probabilities respectively corresponding to different control signals;
[0083] S2. Determine the initial timing range value and value range value corresponding to each control signal specified by the signal transmission protocol;
[0084] S3. Randomly obtain an intermediate timing range value by using the timing probability for the corresponding initial timing range value and randomly obtain an output value by using the value probability for the corresponding value range value;
[0085] S4. Obtain a sampling signal and determine a control signal to be generated according to the sampling signal;
[0086] S5. Randomize the intermediate timing range value of the control signal to be generated to obtain a timing point, and generate the control signal to be generated by using the timing point and the corresponding output value.
[0087] This solution uses SV as the design language and adopts an object-oriented design method to replace the module-based design method. The generation timing and value probability are configurable, and timing randomization and value randomization will be performed according to the configured probability to generate external outputs. Its advantages are that the verification coverage is greatly improved, the convergence speed is significantly increased, and under the condition of generating the same coverage incentives, the dependence on the diversity of external input signal changes is reduced, which helps to discover design defects earlier and more comprehensively in simulation or verification, and reduces risks and human time costs.
[0088] In some embodiments, it can adopt, for example Figure 2 the model shown to implement the method for generating a control signal proposed in the embodiments of the present invention. In the Figure 2 shown axi slave model, its boundary and value module is used to generate the timing boundary value and output value of the signal according to the timing probability and value probability of the external input. The algorithm processing module processes the axi signal sampled by the signal driving module. The signal driving module is used to sample and drive the axi bus. The sampled signal is sent to the algorithm processing module for processing, and the driving part controls the signal driving of the axi bus according to the output of the algorithm processing module. That is, the boundary and value module can receive multiple timing probabilities and value probabilities corresponding to different control signals respectively, and according to the initial timing range value and value range value corresponding to each control signal, randomize the corresponding initial timing range value by using the timing probability to obtain an intermediate timing range value and randomize the corresponding value range value by using the value probability to obtain an output value. The algorithm processing module then randomizes the intermediate timing range value of the control signal to be generated to obtain a timing point and generates the control signal to be generated by using the timing point and the corresponding output value.
[0089] In some embodiments, in step S1, receiving multiple timing probabilities and value probabilities corresponding to different control signals respectively, specifically, as Figure 2 shown, the control signals may include port signals such as awready, wready, bready, arready, rid, rresp, rvalid, etc. stipulated by the axi protocol, and the timing probabilities and value probabilities corresponding to different control signals can all be generated by existing modules.
[0090] In some embodiments, in step S2, determine the initial timing range value and value range value corresponding to each control signal specified by the signal transmission protocol. Specifically, the initial timing range value and value range value corresponding to each control signal are determined by the design indicators specified in the signal transmission protocol.
[0091] For example, for the AXI protocol, if the default timeout is 16 clock cycles, the initial timing range value of control signals such as ready or valid is 0 to 16. Of course, the initial timing range values of other signals can be determined by other parameters of the AXI protocol. Similarly, according to the AXI protocol, the value range value of the ready signal is 0 to 1, the value range value of the valid signal is 0 to 1, and the value range value of the rresp signal is 0 to 3, etc.
[0092] In some embodiments, it further includes:
[0093] Multiply each timing probability and value probability by the same multiple.
[0094] Specifically, for the input timing probability, it is amplified to an integer. For example, 30% is amplified to 30, which means it is increased by 100 times. Similarly, for the value probability, the output value is obtained in the same way, that is, by multiplying by the same multiple to amplify the value probability to an integer. For example, 30% is amplified to 30, which means it is increased by 100 times. Use the system function str_randomize() with {}, and use the amplified integer as the probability constraint for the value range value of the input, randomize the value boundary value, and obtain the output value.
[0095] In some embodiments, randomly obtaining an intermediate timing range value by using the timing probability for the corresponding initial timing range value further includes:
[0096] Determine the probability that each value in the timing range value is randomly selected according to the timing probability.
[0097] In some embodiments, it further includes:
[0098] Obtain the intermediate timing range value by using the randomly selected value and the minimum value in the initial timing range value.
[0099] Specifically, after amplifying the timing probability to an integer, the system function std::randomize() with {} can be used, and use the amplified integer as the probability constraint for the initial timing range value of the input, randomize the timing boundary value, and obtain the intermediate timing range value.
[0100] In some embodiments, determining the probability that each value in the timing range value is randomly selected according to the timing probability further includes:
[0101] Divide the timing probability by a preset size to obtain the probability for each value among multiple values in the timing range value to be randomized, where the preset size is the same as the number of the multiple values;
[0102] Use the value obtained by subtracting the timing probability from 1 as the probability for the remaining values in the timing range value to be randomized.
[0103] For example, if the timing probability is 30%, the boundary value of the middle timing range value is a, and the initial timing range value is 0 - b, then std::randomize(a) with {a dist{[1:b]: / 30, 0 := 70}}, and the value of a can be obtained through the simulator simulation. Then use 0 - a as the middle timing range value.
[0104] Among them, each value in 1 - b has a probability of 30% / b to be randomized, while for the remaining value - 0, the probability for it to be randomized is 70%.
[0105] In some embodiments, using the value probability to randomize the corresponding value range value to obtain an output value further includes:
[0106] Determine the probability for each value in the value range value to be randomized according to the value probability.
[0107] In some embodiments, determining the probability for each value in the value range value to be randomized according to the value probability further includes:
[0108] Divide the value probability by a preset size to obtain the probability for each value among multiple values in the value range value to be randomized, where the preset size is the same as the number of the multiple values;
[0109] Use the value obtained by subtracting the value probability from 1 as the probability for the remaining values in the value range value to be randomized.
[0110] Specifically, after magnifying the value probability to an integer, the system function std::randomize() with {} can be used, with the magnified integer as the probability constraint input for the value range value, to randomize the timing boundary value to obtain the output value.
[0111] For example, if the value probability is 30% and the value range value is 0 - c, then std::randomize(a) with {a dist{[1:c]: / 30, 0 := 70}}, and the output value can be obtained through the simulator simulation.
[0112] Among them, each value in 1 - c has a probability of 30% / c to be randomized, while for the remaining value - 0, the probability for it to be randomized is 70%.
[0113] In some embodiments, in step S5, a random timing point is obtained from the intermediate timing range value of the control signal to be generated, and the control signal to be generated is generated by using the timing point and the corresponding output value. Specifically, after obtaining the intermediate timing range value, std::randomize(c) with {d <= b} can be used, and d, that is, the timing point, can be obtained through the simulator simulation. Then, the signal driving module drives the signals of the axi bus according to the timing point and the output value obtained through the above process. The driving module will follow the axi protocol according to the timing point and value generated by the algorithm processing module, and adopt a way of running five tasks in parallel: write command, write data, write response, read command, and read data, to implement the corresponding axi interface.
[0114] For example, if the previously obtained timing point is c and the output value is d, then repeat(c) @(io.cb); io.cb.wready <= d; is the processing method for the write data ready handshake signal.
[0115] This solution uses SV as the design language and adopts an object-oriented design method to replace the module-based design method. The generation timing and the probability of values are configurable, and timing randomization and value randomization will be performed according to the configured probability to generate external outputs. Its advantages are that the verification coverage rate is greatly improved, the convergence speed is significantly increased, and under the condition of generating the same coverage incentives, the dependence on the diversity of external input signal changes is reduced, which helps to discover design defects earlier and more comprehensively in simulation or verification, and reduces risks and human time costs.
