Flexibility of the Extended Burst-Mode Specification for Synthesis of Speed- Independent Circuits

Due to problems related to the clock signal, asynchronous circuits have become a promising alternative. The Speed Independent (SI) class, asynchronous control circuits, are attractive because they tolerate delay variations resulting from technology migration or temperature variations. These controllers work correctly regardless of individual gates (unbounded gate delay) while assuming zero-delay wires and are highly modular because they interact with the environment in input/output mode. Different specifications were used to describe SI circuits, but these specifications were either unfamiliar to designers or showed limitations in describing SI circuits' potential. This paper proposes a flexibilization of the XBM (Extended Burst-Mode) specification that is familiar to designers to describe SI circuits with operations of signals such as sequencing and concurrency.
