Computer aids for high performance CMOS custom design

Abstract

A set of design tools that creates the framework for a loading-edge full-custom design methodology has been developed. The tools provide the design flexibility and accuracy needed to achieve maximum performance in a quality design. Complex chips with clock rates from 90 MHz to 250 MHz have been economically built using the three latest generations of CMOS processing technologies, sized at 1.75 μm, 1.25 μm, and 0.9 μm
