Abstract
A computer device which performs logic synthesis using hardware description and a component in a cell library and generates a net list of a logic circuit including a series path of a clock synchronous sequential circuit and a combinational circuit performs optimization processing for decreasing the number of gate stages in a critical path between sequential circuits in the data path by using a third sequential circuit having a negative-logic input terminal and a negative-logic non-inverted output terminal and a fourth sequential circuit having a negative-logic input terminal and a negative-logic inverted output terminal in addition to a first sequential circuit having a positive-logic input terminal and a positive-logic non-inverted output terminal and a second sequential circuit having a positive-logic input terminal and a positive-logic inverted output terminal.
