Automated placement for a leaf cell generator

A program for the design of leaf cells for silicon compilers of digital VLSI circuits, is being developed. It uses rule based modules to put together basic circuits, check design rules, check designs constraints and to control each of these constituent tasks. An optimization algorithm, in this case a genetic algorithm, optimizes the layout, under the control of the rule system. The program is divided into modules that can run together using a client-server model.<>
