PREPROCESSOR, DESIGN SYSTEM OF INTEGRATED CIRCUIT, AND DESIGN METHOD OF INTEGRATED CIRCUIT

摘要

PPROBLEM TO BE SOLVED: To provide a preprocessor which generates a circuit description file to change the synchronous/asynchronous designation of a flip flop and cluster connection of a gated clock. PSOLUTION: This preprocessor 23 performs processing of a first circuit description file 21 described by a user and including a first hardware description language and a second hardware description language based on a preprocessor control file 22 described by the user, and converts at least a part described in the first hardware description language of the first circuit description file 21 to the second hardware description language to generate and output a second circuit description file 24. According to this, a circuit description file to change the synchronous/asynchronous designation of the flip flop and the cluster connection of the gated clock is generated without intervention of manual operation.
