The LES expert system for layout generation of random logic modules in a hierarchical CMOS VLSI design system is described. It applies a combination of rule- and algorithmic-based techniques on a novel layout style. The layout style utilizes silicon area more efficiently than a previously developed style. Experimental results have demonstrated the superiority of this expert system against various standard-cell systems and its competitiveness with human designers
