The Topolog module generator is the major circuit-design component of the ASP silicon compiler. Topolog is an attempt to determine the utility of Prolog specifically and logic programming generally for the programming of solutions to large-scale VLSI circuit design problems. We have verified that Prolog's clause-based programming style permits easy extensibility of VLSI module generators for new technologies and user-written macroblocks. We have demonstrated that Prolog, even without the well-known assert retract, and write operators is not a pure applicative language. We have devised a method of type definition in Prolog, and have preliminary evidence that our method is superior in efficiency to the general term unification method commonly found in the literature.
