摘要

PROBLEM TO BE SOLVED: To suppress the formation of a critical path and to reduce a chip area. SOLUTION: This logic synthesizer is provided with a subdividing means 111 for subdividing a module defined within a hardware function description by respective functions and generating subdivided modules, a hierarchizing means 112 for converting the hardware function description to two hierarchies, a rearranging means 114 for rearranging the subdivided modules in the direction of reducing bypass wiring and long distance wiring, a grouping means 115 for grouping the rearranged subdivided modules based on the prescribed condition that a virtual wiring model functions and generating an intermediate hierarchy within the hardware function description converted to the two hierarchies and a synthesizing means 116 for performing a logic synthesis processing to the hardware function description in which the intermediate hierarchy is generated.
