SEMICONDUCTOR INTEGRATED CIRCUIT DEVICE, RECORDING MEDIUM STORED WITH CELL LIBRARY, AND METHOD FOR DESIGNING SEMICONDUCTOR INTEGRATED CIRCUIT

摘要

ÄObjectÜ To provide a semiconductor integrated circuit device constructed of MOSFETs in which there is attained a harmony between increase in consumption power due to a leakage current and operating speed of the MOSFETs in a suitable manner. ÄConstitutionÜ Among a plurality of signal paths in the semiconductor integrated circuit device, a path which has a margin in delay is constructed with MOSFETs each with a high threshold voltage, while a path which has no margin in delay is constructed with MOSFETs each with a low threshold voltage which has a large leakage current but a high operating speed, in light of a delay with which a signal is transmitted along a signal path.
