TIMING ANALYZING DEVICE, TIMING ANALYZING METHOD, TIMING ANALYZING PROGRAM AND COMPUTER-READABLE RECORDING MEDIUM WITH THE TIMING ANALYZING PROGRAM RECORDED THEREON

摘要

PPROBLEM TO BE SOLVED: To provide a timing analyzing device for reducing the number of ECO parts. PSOLUTION: A timing analyzing device 1 includes an instance list creating part 12 configured to create an instance list including an instance existing between logic circuits in a path report and a slack value; an instance list report creating part 14 configured to create an instance list report including a plurality of instance lists; a maximally appearing instance determining part 16 configured to determine an instance which most frequently appears, and which appears the last as a maximally appearing instance; a worst slack value determining part 18 configured to determine a worst slack value from an instance list including the maximally appearing instance; an ECO determining part 20 configured to determine an ECO place and ECO value from the maximally appearing instance and the worst slack value; and a deleting part 22 configured to delete the instance list including the maximally appearing instance.
