The paper introduces the concept of asynchronous pseudo-system. Its purpose is to correct/generalize/continue the study of the asynchronous systems (the models of the asynchronous circuits) that has been started in [1], [2].

Complexity of design and testing are the major obstacle for widespread use of asynchronous circuit in digital circuit design. Template based synthesis of asynchronous circuit is accepted as an effective way to decrease complexity of design of asynchronous circuit. One of the popular pre-designed templates that most synthesis tools use it to synthesis QDI asynchronous circuit is Pre-Charged Full...

Asynchronous circuits are widely used in many real time applications such as digital communication and computer systems. The design of complex asynchronous circuits is a diicult and error-prone task. An adequate synthesis method will signiicantly simplify the design and reduce errors. In this paper, we present a general and eecient partitioning approach to the synthesis of asynchronous circuits...

Asynchronous circuit design has been studied for decades, but it has only recently been feasible to construct large and e cient asynchronous systems. This paper surveys di erent techniques for checking whether an asynchronous circuit has fabrication defects. The inherent di erences between asynchronous and synchronous circuits, primarily that asynchronous circuits do not have a global clock, ne...

Conventional asynchronous control circuit design is complex because potential designs must be analysed for the existence of hazards and state variable races, as these may cause incorrect circuit operation. We present the innovative CMOS direct-mapped asynchronous circuit design approach, which, by defining a one-to-one mapping between state diagram and CMOS circuit implementation, removes the n...
