Abstract: | In this paper we introduce the notion of weak endochrony, which extends to a synchronous setting the classical theory of Mazurkiewicz
traces. The notion is useful in the synthesis of correct-by-construction communication protocols for globally asynchronous,
locally synchronous (GALS) systems. The independence between various computations can be exploited here to provide communication
schemes that do not restrict concurrency while still guaranteeing correctness. Such communication schemes are then lighter
and more flexible than their latency-insensitive or endo/isochronous counterparts.
