Scheduling with environmental constraints based on automata representations

We introduce a framework in which design information can be represented using an automaton model. We present a novel scheduling algorithm under environmental constraints where both the design and constraints are represented using automata. This model offers the advantage of supporting different constraints (e.g. timing, resource, synchronization, etc.) with a uniform formalism. All feasible schedules are captured with a single product automaton. The automaton is constructed and traversed using efficient BDD-based implicit state-traversal techniques. We present an algorithm that generates a minimum-latency schedule. This approach is able to exploit degrees of freedom among interacting components of a multi-module system during scheduling.<
