ABSTRACT:
Standard cell libraries and methods of designing semiconductor integrated circuits are provided. At least one of delay-adjusting cell data and load-capacitor cell data is stored in the cell library for a specified type standard cell in addition to the standard cell data. The specified type standard cell may be utilized as a delay-adjusting cell or a load-capacitor cell. Accordingly, precise adjustment of delay times during designing a semiconductor integrated circuit is enabled without requiring registering a new standard cell in the cell library. Semiconductor integrated circuits are also provided that are configured to allow precise adjustment of delay times in the semiconductor integrated circuits.
