A path-oriented approach for reducing hazards in asynchronous designs

The authors describe a path-oriented approach for analyzing hazards in an asynchronous circuit that is synthesized from a specification in the form of a signal transition graph. They also describe a technique to avoid hazards by adjusting the delays in a circuit rather than doing this piecewise for each path. It is shown that improved results can be obtained by solving an appropriately formulated linear programming problem. In addition to the benefits of working at a higher level of abstraction, this method handles some classes of dynamic hazards in addition to static hazards.<
