Computing Science: Interactive Resolution of Encoding Conflicts in Asynchronous Circuits Based on STG Unfoldings Technical rept. series

摘要

The synthesis of asynchronous circuits from STGs involves the resolution of encoding conflicts by means of refining the STG specification. The refinement process is generally done automatically using heuristics and offers little or no feedback to the designer making it difficult to intervene. Better synthesis solutions are obtained by involving human knowledge into the process. A framework is presented for an interactive refinement aimed to help the designer. It is based on the visualisation of several types of conflict cores, showing the cause of the encoding conflicts, which are presented at the level of finite and complete prefixes of the STG unfolding.
