Abstract

A synchronous circuit design is converted to an asynchronous circuit by converting synchronous circuit logic to an asynchronous circuit logic, and converting one or more asynchronous inputs at a circuit boundary to an asynchronous input to the converted asynchronous circuit logic, such that the converted asynchronous input is operable to generate a token upon observing a change in state on the asynchronous input. One or more asynchronous outputs at a circuit boundary is converted to an asynchronous output from the converted asynchronous circuit logic, such that the converted asynchronous output is operable to output updated data as soon as changed data is received from the converted asynchronous circuit logic in the asynchronous output.
