Abstract

An automatic/interactive layout Computer Aided Design (CAD) system for designing master-slice LSI chips, is presented which places function blocks and gives wiring patterns on the chip. Since 100% routing is essential for master-slice layout design, it is urgently required to establish a strong CAD system that significantly reduces the design time. The LAMBDA system has been developed to achieve complete net connectivity in as short a design time as possible, where efficient automatic procedures are implemented as well as highly interactive functions. The system adopts two-level hierarchical algorithms for placement and routing problems. Furthermore, highly interactive functions are realized by exploiting human intelligence and the computer's high speed processing.
