Abstract

Constrained encoding has several applications in the synthesis of finite state machines (FSMs). E.g., it can be used to generate asynchronous FSM state assignment that guarantees a critical hazard-free implementation, or to generate synchronous FSM state assignment with minimum PLA implementation. This paper presents ZeDicho, an original zero-suppressed binary decision diagram (ZBDD) based algorithm that solves exactly the dichotomy-based constrained encoding problem.
