Path programmable logic (PPL) is an integrated circuit design methodology offering small layout areas, greatly reduced design time, and a high degree of technology independence. In this paper, the structure of PPL is presented, and the details of one implementation, static CMOS PPL, are shown. A conceptual model of PPL design using truth and state tables is given. A database format is presented, and the design system using this database is described. Benchmarks comparing PPL to other design methodologies show PPL compares favourably with custom design in terms of layout area while providing significant savings in design time.
