irun ams flow -- error from spectre model

Steven Mikes

I'm trying to run a mixed-signal simulation with the irun (command line) flow. I think everything is set up correctly (followed the documentation / examples in irun install dir). I'm getting flooded with the following errors when trying to run the sim:

amsspice: *Warning (/afs/eecs.umich.edu/kits/TSMC/N45GS/2015.01/lv1p10p7x0y1z0r1u/tsmcN45/../models/spectre/./crn45gs_1d8_ud15_lk_v2d0_2.scs,90302): Function 'pwr' is not supported.
      A default number 0.0 is used to replace this function.

This is actually a warning, not error, but it throws the error later when the model file take the natural log of the number that was supposed to result from the pwr() function (now helpfully set to zero).

irun -version
TOOL:    irun    12.20-s012

spectre -V
@(#)$CDS: spectre  version 12.1.0 32bit 05/02/2013 03:12 (usimamd64-28) $

Thanks in advance!

    I believe this is fixed in the INCISIVE14.2 release.
