createCapacityConstrainedModel () Create a new timed HSDF graph in which every actor 'a' of the original graph 'g' belongs to a cycle consisting of the actor 'a' and a new actor 'aMCM'. This cycle contains one initial token and its cycle mean is equal to the MCM of the graph g when g is executed without auto-concurrency.

modelBufferSizeInSDFgraph () Create a new timed SDF graph in which channel sizes are modelled through explicit channels (all buffer sizes are set to unbounded).

modelCapacityConstrainedBuffer () Create a new timed HSDF graph in which channel sizes are modelled through explicit channels (all buffer sizes are set to unbounded). The function 'getStorageSpaceChannel()' on each channel gives a pointer to the channel in input graph g for which the storage space is determined.
