Assura 3.1.6 USR1 - Assura DRC drc.rul file error?

canuck

I'm setting up Cadence IC 5.1.41_USR5 using Assura 3.1.6_USR1 and I'm doing a simple Assura DRC on a basic inverter structure just for test purposes. The technology is IBM_PDK cmrf8sf 130nm from CERN. The error I get when I try a simple DRC is:

It seems like it's having trouble with the geomGetLayerBBox function. I get this error in IC6.1 as well. I'm thinking this could be an error in the actual drc.rul file because I can find info on functions named geomGetBBox, but only the function geomGetLayerBBox. 

This could also be that a newer version of Assura uses this geomGetLayerBBox function and I need to upgrade my Assura version. Any help would be appreciated.

 

Thanks,

    I'm using IBM CMOS8RF V1501 from MOSIS and I get these same messages using IC5141 and ASSURA317. One thing you need to do is in Assura DRC, add the switch corresponding to your BEOL stack. For example, my Switch Names field reads: BEOL_STACK_323 GridCheck ext_latchup. I read on the MOSIS forum that this solved the messages for someone, but I still get them... It still does a full DRC check, and I can clear both Calibre and Assura.
