Abstract
Abstract : This invention relates to computer-aided design (CAD) techniques to generate custom LSI and VLSI devices. The development and increased application of LSI and VLSI devices has resulted in considerable activity in the area relating to the effective and economical design of such circuits. One of the principal fields in which this activity has focused is in the development of CAD techniques to reduce the cost and design time of complex and sophisticated custom LSI and VLSI devices using various technologies. While many computer-aided solutions to these design problems have been offered, these methods have generally failed to meet the demands imposed by improved manufacturing capabilities which permit smaller and more dense circuit layouts. As the logic layout becomes increasingly complex, new solutions must be provided in order to maintain the cost and design effectiveness of computer-aided approaches. (Author)
