Abstract

Synthesis of asynchronous circuits from Signal Transition Graphs (STGs) involves solving state coding conflicts. The refinement process is generally done automatically using heuristics and can often produce a sub-optimal solution, which has to be corrected manually by the designer. This paper presents a framework for an interactive refinement process aimed to help the designer. Rather than using actual conflicts, the process is based on the visualisation of conflict cores. Cores are sets of transitions causing state coding conflicts, which are represented at the level of a finite complete prefix (unfolding) of STGs.
