Abstract

The authors implemented a 3-2 route scheme and overlap allowance in the automatic generation of custom cells layout targeted at GaAs and CMOS technology which requires three or more metal layers. The goal of this system is to create a dense layout with minimum area as the first concern and to have better performance than hand drawing and standard cell approaches. The system intends to solve the routing problems encountered by the conventional two-layer routing and nonoverlap methodology. The structured routing and placement scheme allows the users a choice in the algorithms used for the design process. The system has the capability to be expanded to perform the multiple-row cell layout and the automatic creation of a primitive library with different technologies
