What's the equivalent of Cadence pPar in Mentor Flow?

[safwatonline]

Hello,
i am using mentor flow, and i have a schematic cell view containing a variable, when i instantiate this cell in a higher hierarchical level i want to be able to give different instants different values of that variable.
i used to do it in cadence using pPar, so how to perform the same function in mentor.
thnx
