HDL Simulator Licenses

The HDL simulator can only be invoked for one HDL primary design unit, like an entity or a module. So for each HDL cosimulation model, a different HDL simulator is invoked, which uses an independent license. Currently, there is no way to save/restore the state from one entity to another. However, you can collect all the adjacent HDL cosimulation models into one top-level HDL entity and generate one HDL cosimulation model for that entity.

The ADS HDL cosimulation feature has an independent license. Only one license is required for a design that has more than one HDL cosimulation model.
