Abstract :
FPGAs have been mainly used for design of synchronous circuits. It is, however, difficult to design asynchronous circuits on them because the circuit may suffer from hazard problems. We propose a method that implements a popular class of asynchronous circuits, known as extended burst- mode, on FPGAs based on look-up table architectures. We state a sufficient condition so the implementation in FPGAs becomes essential hazard-free. By doing that, asynchronous circuits, besides their intrinsic advantages over synchronous ones, may also take advantage of integration, lower costs and design short-time associated with FPGA designs.
