INTEGRATED CIRCUIT DESIGN METHOD, DESIGN DEVICE AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To design an insulation recycling logic circuit so as to minimize power consumption.SOLUTION: An integrated circuit design method includes the steps of: grouping logic cells of an insulation recycling logic circuit into M (M≥N) logic cell subsets according to each logic depth; moving at least one logic cell of multiple grouped logic cells and changing a logic cell subset that at least includes the logic cell, so as to increase the number of logic cells included in at least one of the logic cell subsets; determining each logic cell set as one of the M logic cell subsets or as a sum set of two or more logic cell subsets; assigning N power clock signals to N logic cell sets determined; and determining each of the logic cell sets so that a logic cell included in at least one logic cell subset with the number of logic cells increased becomes a logic cell of a first stage in a logic cell set circuit.
