Abstract

Abstract--A self-timed programmable architecture used for the implementation of Phased Logic (PL) systems is described. PL systems are automatically translated from clocked designs and result in self-timed circuits that are insensitive to delays between gates. The target implementation is a self-timed FPGA architecture composed of PL gates. A PL gate design based on a 4-input lookup table is presented. Power and performance estimates of two designs are given and are compared to their clocked counterparts.

Phased logic has been proposed as
