pcellEvalFailed when I change my cadence version

Hi Andrew,

I am trying to run the post layout simulations for my project. Everytime I run Assura QRC it fails, I tried to change the cadence version from 6.1.7 to 6.1.5 to see if it works or not, but when I open the layout which is DRC and LVS clean, the compnents are disappeared and I cannot event bring them manually in the layout and the following warning/error pops up:

WARNING* (DB-270001): Pcell evaluation for PRIMLIB/ne/layout has the following error(s):

*WARNING* (DB-270002): ("eval" 0 t nil ("*Error* eval: undefined function" XpcInitMosfet))

*WARNING* (DB-270003): Error kept in "errorDesc" property of the label "pcellEvalFailed" on layer/purpose "marker/error" in the submaster.

Do you have any suggestions that what is happening?

Regards,

Mehdi
