A cell and macrocell compiler for GaAs VLSI full-custom design

Abstract

A gallium arsenide automated layout generation system (OLYMPO) for SSI, MSI and LSI circuits used in GaAs VLSI design has been developed. We introduce a full-custom layout style, called RN-based cell model, that it is suited to generate low self-inductance circuit layouts of cells and macrocells. The cell compiler can be used as a cell library builder and it is embedded in a random logic macrocell and an iterative logic array generator. Experimental results demonstrate that OLYMPO generates complex and compact layouts and the synthesis process can be interactively used at the system design level.
