The authors describe a new approach to custom LSI layout. This approach, called custom cell array, has a big advantage over conventional custom design approaches, incorporating custom cell array generator, automatic or interactive layout programs and a chip image optimizer. Several experimental results are shown, indicating the effectiveness of the approach. A 12% reduction in layout area size is achieved, compared with a conventional poly cell layout approach, and a 29-62% reduction is achieved, compared with the gate array approach.
