Abstract:	The paper introduces Lazy Transitions Systems (LzTSs). The notion of laziness explicitly distinguishes between the enabling and the firing of an event in a transition system. LzTSs can be effectively used to model the behavior of asynchronous circuits in which relative timing assumptions can be made on the occurrence of events. These assumptions can be derived from the information known a priori about the delay of the environment and the timing characteristics of the gates that will implement the circuit. The paper presents necessary conditions to synthesize circuits with a correct behavior under the given timing assumptions. Preliminary results show that significant area and performance improvements can be obtained by exploiting the extra "don't care" space implicitly provided by the laziness of the events.
