MODEL CREATION DEVICE FOR HIGH SPEED HARDWARE SIMULATION AND SIMULATION DEVICE THEREFOR

摘要

PPROBLEM TO BE SOLVED: To provide a model creation device for high speed hardware simulation for quickly executing simulation by converting a model described in hardware operation description language into simulation description. PSOLUTION: RTL description is divided into sequential circuit description (1c) and combinational circuit description (1b), the divided sequential circuit description (1c) is processed into combinational circuit description, and simulation description is reconfigured from the divided combinational circuit description (1b) and the processed combinational circuit description. No sequential circuit is included requiring arithmetic operation for each clock event, and update of input variables other than the clock triggers an arithmetic operation in simulation in stead of a clock event, so that it is possible to generate simulation descriptions for suppressing the frequency of the arithmetic operation.
