As far as I know, PCM cannot be modeled explicitly in IESVE. Supposedly you can approximate its behavior by following these guidelines:

I haven't tried this method myself, but I'd be reluctant to put too much faith into the results.
In my opinion, EnergyPlus is the best building simulation tool for modeling PCM.
