Abstract
A method of asynchronous circuit synthesis of initializable circuits from signal transition graphs (STG) that are either functionally initializable or functionally uninitializable is described. For functionally initializable cases, an initializable implementation can be achieved by proper assignment of don't care values. If the STG is not functionally initializable, the sources of uninitializability in the STG are identified and the STG is transformed into a functionally initializable specification by exploiting concurrency. Initializability is achieved at the expense of minimal removal of concurrency. Moreover, the transformation does not violate liveness and unique state coding properties of the STG. When the STG is functionally initializable or after an uninitializable STG is transformed to become functionally initializable the result is an initializable circuit design.
