This paper presents a straightforward approach for synthesizing a standard VHDL description of an asynchronous circuit from a behavioural VHDL description. The asynchronous circuit style is based on 'micropipelines', a style currently used to develop asynchronous microprocessors at Manchester University. The rules of partition and conversion which are used to implement the synthesizer are also described. The synthesizer greatly reduces the design time of a complex micropipeline circuit. © 1998 IEEE.
