This flexible tool provides automated or interactive layout of both 'mass-production' and custom logic IC's for a variety of MOS technologies. The layout process accommodates 2 or 3 routing layers, signals of different widths and produces power and ground connections entirely on a single layer. Additionally the system allows its algorithms to be controlled and directed so that it can be highly tuned to a particular application. The system is integrated with other Integrated Circuit Design aids such as GAELIC, TARTAN and CHECK.10.2312/eg.19821023
