摘要：A circuit design support apparatus for supporting design of a semiconductorintegrated circuit includes an upper limit path delay determining unit that sorts circuit

paths included in the semiconductor integrated circuit by probability distributions for thedelay values of the circuit paths, selects a worst path having a largest delay value in thecircuit paths, and determines a maximum delay value as an upper limit path delay valuethat does not affect an operational timing of the semiconductor integrated circuit, a cellsize optimization processor that replaces cells by modifying their cell sizes on the basisof the upper limit path delay value, and a critical path determining unit that determinescritical paths that are capable of affecting the upper limit path delay value if the cell sizeoptimization processor replaces cells included in the circuit paths.
