Abstract: We propose a design flow for asynchronous circuits that closely mimics the standard synchronous ASIC design flow. Key elements of the flow are HDL-based specification, logic synthesis and physical design. In this work we present a proposal for using a standard HDL, Verilog, to specify an asynchronous control circuit at the behavioral level. This specification is automatically translated in a Signal Transition Graph, that can then be automatically synthesized by existing tools. Advantages of this methodology include rapid path to implementation, re-use of simulation patterns, between pre- and post-synthesis steps, and designer familiarity with the specification language.
Keywords: Verilog HDL, asynchronous circuit design, signal transition graphs, synchronous circuit design.
