Abstract

The major problems associated with LSI design include those of design complexity, documentation, mapping, design verification both functional and physical, physical implementation, and the manufacturing interface. The Design Aids group at Burroughs, Cumbernauld, have developed an integrated LSI design system, CELTIC, which solves these problems with a polycell design approach, direct graphics entry of logic diagrams, and automatic generation of LSI layouts. The system reduces the time required to lay out LSI's from months to weeks.

A Layout System for the Random Logic Portion of an MOS LSI Chip

The random logic portion of an MOS LSI chip intended mainly for a calculator is constructed of an array of MOS complex gates, each composed of an MOS ratioless circuit with a multiphase clocking system, and occupies ordinarily a considerable part of ...
Design of Self-Checking MOS-LSI Circuits: Application to a Four-Bit Microprocessor

Self-checking approaches developed so far deal with a gate level representation of logical circuits. They do not account for constraints which may result from an implementation by integrated circuits. This paper is concerned with such practical problems ...
An integrated computer-aided design system for custom LSI circuits

An integrated computer aided design system for the design, layout and layout verification of integrated circuits is described. The imagery required for photofabrication of an integrated circuit is created by computer from a place and interconnect data ...
