For Assura, all you should need to do is to:
That's it. For Calibre, you should read the Mentor documentation - but it's a matter of setting appropriate UNIX env vars, setting up your path, and loading some code from your .cdsinit (if my memory is correct).
Neither of these things is something that the PDK would take care of, I believe - it's more of a software installation/setup problem.

Thank you very much Indeed Andrew.
In reply to wgtkan:
This didn't work for me. Do you need to have anything else in the .cdsinit etc?
In reply to NKU10k:
Assura doesn't require anything in .cdsinit . Calibre probably does, but that's a question for Mentor.
Make sure you're using an OA version of Assura with an OA version of Virtuoso or a CDB version with a CDB version of icfb (i..e pick the appropriate version of Assura when you install it).
