ABSTRACT:
A design method for an asynchronous sequential circuit that employs synchronous design techniques wherein a synchronous sequential circuit is designed to perform a desired function. A terminating state for the synchronous sequential circuit is then defined wherein the terminating state occurs before a transition to an idle state in the synchronous sequential circuit. A circuit is provided for latching at least one asynchronous input for the asynchronous sequential circuit and a circuit is provided for generating a synchronous clock that drives the synchronous sequential circuit such that the synchronous clock is enabled by a latched asynchronous input and is disabled by the terminating state of the synchronous sequential circuit.
