Detailed Description

This class models the most basic scheduling problem.

A problem instance is comprised of:

Operations: The vertices in the data-flow graph to be scheduled.
Dependences: The edges in the data-flow graph to be scheduled, modeling a precedence relation between the involved operations.
Operator types: An abstraction of the characteristics of the target representation, e.g. modules in the HLS component library, available functional units, etc. – operations are executed on instances/units of an operator type.

Operations and operator types are stored explicitly. The registered operations induce a subgraph of the SSA graph. We implicitly include the dependences corresponding to its def-use relationships in the problem, e.g. if operation y's second operand uses the first result produced by x, we'd have a dependence x:0 --> y:1. Clients can additionally register explicit, auxiliary dependence between operations, e.g. to encode memory dependencies or other ordering constraints. Auxiliary dependences do not distinguish specific operands/results. The differences between the flavors are transparent to concrete algorithms.

All components of the problem (operations, dependences, operator types, as well as the instance itself) can be annotated with properties. In this basic problem, we model

linkedOperatorType maps operations to their operator types.
latency, an operator type-property denoting the number of time steps after which the operator's result is available.
startTime, an operation-property for the time step in which an operation is started. Together, the start times for all operations represent the problem's solution, i.e. the schedule.

Subclasses, i.e. corresponding to more complex scheduling problems, can declare additional properties as needed. The check... methods perform validity checks before scheduling, e.g. that all operations have an associated operator type, etc.

The verify... methods check the correctness of the solution determined by a concrete scheduling algorithm, e.g. that there are start times available for each registered operation, and the precedence constraints as modeled by the dependences are satisfied.
