Embodiment 1
[0029] figure 1 A schematic structural diagram of a verification system for cooperating among integrated circuit modules provided by Embodiment 1 of the present invention. This embodiment is applicable to verifying the cooperating ability between core function modules under the condition that the interconnection circuit of the core circuit modules is not completed. Circumstances for verification. Such as figure 1 As shown, the verification system for cooperating among integrated circuit modules specifically includes: a stimulus model 10 , a function simulation model 20 , an interconnection circuit model 30 , a memory model 40 and a scoreboard 50 . in,
[0030] The stimulus model 10 is used to generate the command set of the circuit module under test 60, the interconnection circuit model configuration information and the memory model configuration information, and send the command set to the host circuit module 61 and the function simulation model 20 respectively, and transfe...
Embodiment 2
[0080] image 3 Embodiment 2 of the present invention provides a flow chart of a method for verifying collaborative work between integrated circuit modules. This embodiment is applicable to verifying the collaborative work capability between core function modules under the condition that the interconnection circuit of the core circuit modules is not completed. The case of verification. The method can be executed by a verification system that cooperates among integrated circuit modules provided by an embodiment of the present invention. The system can be implemented in software and / or hardware, and can generally be integrated into a computer.
[0081] Such as image 3 As shown, the method of this embodiment specifically includes:
[0082] S210. Generate the instruction set of the circuit module under test, the interconnection circuit model configuration information, and the memory model configuration information through the excitation model, and send the instruction set to th...
Embodiment 3
[0123] Figure 4 It is a schematic structural diagram of a verification system for cooperating among integrated circuit modules provided by Embodiment 3 of the present invention. This embodiment provides a specific implementation manner.
[0124] refer to Figure 4 , the circuit under test in this embodiment may be a computing unit cluster (CLUSTER) in an artificial intelligence chip, and each CLUSTER has a host interface circuit and a slave interface circuit. The data transmission protocol can be AXI4.0 (Advanced eXtensible Interface is a high-performance, high-bandwidth, low-latency on-chip bus in the AMBA-Advanced Microcontroller Bus Architecture protocol proposed by ARM). Specifically, the tested circuits are two CLUSTER instances, respectively C0 and C1, wherein C0 is used as a master circuit module, and C1 is used as a slave circuit module.
[0125] First, the stimulus model writes the set of instructions into C0. Secondly, C0 executes the instruction set, and writes...
