Obtaining logic minimization for asynchronous controllers synthesis to digital design course

Synchronous digital systems have been presenting serious problems of implementation in DSM (deep sub-micron) VLSI technology. The asynchronous paradigm has become an interesting alternative. Unfortunately, the topic of asynchronous circuits has been ignored in most university courses. An important step in the synthesis of asynchronous controllers is the logic minimization. Several algorithms were proposed, some of them are not available to students and usually they are complex to apply manually. In this paper we propose a simple method to perform logic minimization starting from XBM controllers. The simplicity of the method and its optimization capacity permit the students to apply it manually in any moment of a digital basic course.
