Incomplete schedule models found.
- Consider setting 'CompleteModel = 0' while developing new models.
- Pseudo instructions can be marked with 'hasNoSchedulingInfo = 1'.
- Instructions should usually have Sched<[...]> as a superclass, you may temporarily use an empty list.
- Instructions related to unsupported features can be excluded with list<Predicate> UnsupportedFeatures = [HasA,..,HasY]; in the processor model.

error: Incomplete schedule model
