The paper presents a new gate matrix layout system: GMS for VLSI CMOS circuits. GMS can be used as a cell generator to produce basic cells automatically. The whole layout procedures in GMS are divided into gate assignment, net assignment and compaction. 本文介绍一个新的VLSICMOS电路栅阵列布图系统GMS(GateMatrixlayoutSystem),它可以作为单元生成器在VLSI布图中自动产生基本单元。
