Verilog HDL, powered by PLI: a suitable framework for describing and modeling asynchronous circuits at all levels of abstraction

Abstract

In this paper, we show how to use Verilog HDL along with PLI (Programming Language Interface) to model asynchronous circuits at the behavioral level by implementing CSP (Communicating Sequential Processes) language constructs. Channels and communicating actions are modeled in Verilog HDL as abstract actions.
