Title: Lsi layout design system
Inventor: YAMASHITA SHIGERU
IPC: H01L21/82
Filed: 2000-09-14
Abstract: PROBLEM TO BE SOLVED: To reduce signal delay time which is caused by micronizing processes in an LSI circuit and reduce the number of reattempting times of layout design. SOLUTION: In layout design of an LSI, a net list of an LSI circuit is inputted in a computer. The computer inspects on the net list whether wiring inputted to a subcircuit constituting the LSI circuit or wiring outputted from the subcircuit is made to branch. In the case that the wiring is made to branch, a buffer selected by a designer is inserted automatically in a subcircuit in the front of a branch point (in the case of input) or in the rear of the branch point (in the case of output). When buffers are presented to the designer, display is performed in the order of good result. As a result, adverse influence due to wiring length upon signal delay time is divided by the buffer, so that signal delay time is shortened. The subcircuit can be made a black box, so that the number of reattempting times of layout design can be reduced.
