DESIGN METHOD OF SEMICONDUCTOR CIRCUIT AND SEMICONDUCTOR CIRCUIT DESIGNED BY MEANS OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide the design method of a semiconductor circuit easy in regulating a skew between clock trees and the semiconductor circuit designed by means of it. SOLUTION: After a net list is prepared S1, a plurality of delay gates are previously inserted S1' on the net list, and deleted S7 while the delay gate is regulated so as to satisfy the restriction of timing between clock trees.
