Synchrony
Basics operation: At each clock tick, each module reads input, computes and produces outputs simultaneously.
? zero delay calculations, infinite time between ticks.(no cyclic dependencies among values of events with same tag)
Triggering and ordering: All modules are triggered to compute at every clock tick. At each clock tick, there is no ordering of reading of inputs, computation or writing outputs. However, an ordering can be imposed with delta step (delay) concept.
? zero time that passes between events at the same clock tick and that serves simply to order events.
