Abstract

The invention provides a CPU configuration device, a CPU configuration method and a chip simulation method. The CPU configuration method is applied to configure a tested object through a CPU configuration engine during chip simulation, and the tested object is provided with a plurality of sub-modules connected with a CPU. The method comprises the following steps: configuring a CPU configuration engine for each sub-module connected with the CPU; and configuring each sub-module based on each CPU configuration engine. Multiple CPU configuration engines are copied in an instantiated mode and connected to each independent sub-module with the CPU configuration interface, parallel downloading of configuration of multiple sub-modules is completed, and then the simulation time of each test case is shortened. Meanwhile, multiple APIs are supported for the user to conduct expansible programming, a backdoor access mode is matched for each CPU configuration engine, the configuration efficiency is further improved, the configuration time is shortened, and testing of more test cases is completed within the same time.

Description

technical field [0001] The invention relates to the technical field of integrated circuits, in particular to a CPU configuration method, a CPU configuration device and a chip simulation method. Background technique [0002] In the application-specific integrated circuit (ASIC) verification process, according to the level of division, we generally call it the chip system level (chip level / system level), subsystem level (sub-system level) and module level (module level / unit level) ), the advantage of this is that it is convenient to disassemble the functional modules, realize parallel work and collaboration of personnel, and improve the execution efficiency of the project. Considering both design and verification, the appropriate complexity module also helps to estimate the appropriate workload and personnel allocation. The design is finally integrated through modularization, and after the verification environment is modularized, it can also be easily implemented in more advan...
