Title: Wiring method in layout design of semiconductor integrated circuit, semiconductor integrated circuit and functional macros
Inventor: FUKUI MASAHIRO
IPC: G11C11/41
Filed: 2002-02-19
Abstract: PROBLEM TO BE SOLVED: To suppress operation failures of a semiconductor integrated circuit due to increase of delay caused by signals changed to antiphase while propagating on two adjacent parallel wirings among a plurality of parallel laid wirings, with reducing the increase of the area. SOLUTION: For laying e.g. 6-bit wirings, wirings 10 of three less significant bits of a high signal change frequency and wirings 20 of three significant bits of a low signal change frequency are alternately disposed to lay the wirings 20 of significant bits, each sandwiched between the right and left wirings 10 of less significant bits. Thus the wiring 20 of significant bit lines acts on the wiring 10 of less significant bit lines as a shield wiring against the signal change. This effectively suppresses the increase of the delay caused by signals changed to antiphase while propagating on the wirings 10 of less significant bit lines.
