Currently, complex FPGA designs typically contain multiple sub-modules below the top-level module. These modules ensure correct functional implementation, but because they are integral parts of the design, they are also subjected to gate-level behavioral simulation during simulation. If a module under test has one top-level module and nine sub-modules, seven of which are library or mature modules, and only two are newly designed modules, then only 30% of the gate-level behavioral simulation computation performed by EDA tools is truly for the part we want to verify. However, due to the existence of the top-level code and the need to verify the interface relationships between modules, the verification of sub-modules cannot replace the verification of the top-level module. If we could allow gate-level behavioral simulation to skip library and mature modules, it would significantly reduce the computational load of gate-level behavioral simulation and improve the speed of FPGA code functional simulation. This invention, for functional verification of FPGA code containing multiple sub-modules, uses a C model to replace the library IP modules or mature modules, preventing these modules from participating in the gate-level behavioral simulation during functional simulation execution, thereby significantly shortening the functional simulation execution time and accelerating the functional verification speed of FPGA code.
