The paper is concerned with the timing analysis of a class digital systems we call mixed asynchronous synchronous systems. In such a system, each computation module is either synchronous i.e. clocked or asynchronous i.e. selftimed. The communication between modules is assumed to be selftimed for all modules. We i n troduce a graph model called MASS for describing the timing behaviour of such architectures. The graph contains two kinds of nodes, synchronous and asynchronous nodes. The operation

The operation model of a MASS is similar to that of a timed marked graph, however, additional schedule constraints are imposed on synchronous nodes: A synchronous node can only re at ticks of its local module clock. We analyze the behaviour of MASS, in particular period, periodicity and maximal throughput rate.
