A hardware description languages (HDLs) based modeling technique for asynchronous circuits is presented in this paper. A HDLs handshake package has been developed for expressing handshake-style digital systems in both VHDL and Verilog. Burst-mode and extended burst-mode (BM/XBM) circuits were used to demonstrate the usefulness of this work. This research successfully prototyped comparators, adders, RSA encoder/decoder, and several self-timed circuits for the full-custom IC and FPGAs designs. Furthermore, the HDLs handshake package implemented by this research can be utilized to develop behavioral test benches for studying and analyzing asynchronous designs. Extracting detailed timing information from asynchronous finite state machines (AFSMs), detecting delay faults for synthesized self-timed functional modules, and locating fundamental mode violation within realized AFSMs are proven applications. The anticipated HDL modeling technique and the transformation procedure are detailed in the rest of this paper.
