Hi,

I installed NCSU_CDK 1.4 in Fedora 3.0. I use IC 5.0.33. When I do
extract on my Layout, I see the following error message. Does this
mean I didn't install NCSU library correctly? Can NCSU 1.4 work with
Fedora 3.0 and IC 5.0.33?

thanks,
Liang-Kai

Hi,

I ran into the same problem, IC50.33 doesn't work with the NCSU kit on Linux (at least for Extraction with ami06).

I found a workaround by removing some extraction rules. See here for the updated file and another thread of the same problem:

thanks

Thanks for the test case. I was able to find the problem and adjust the
rules compiler to handle it.

Every coefficient is zero for elec to metal2. The rule compiler was
changed to skip the processing steps with a coefficient of zero since
they won't produce anything and was skipping them all. This caused the
message about an invalid multiLevelParasitic rule.

The techfile for the PDK should be corrected to have meaningful values,
but that's up to the NCSU people.

The rule deck is also odd in that it has duplicate cap clauses for elec
to metal2, and for elec to metal1.

Hi Ed,

thanks so much for fixing this Diva problem.

I posted a patch to the NCSU PDK 1.4 here:
http://www.chiptalk.org/modules/newbb/viewtopic.php?topic_id=53

To summarize, Ed fixed 2 bugs in the NCSU PDK:
- Syntax error in divaDRC.rul
- Diva Extraction fails under IC51-41

Patches for both bugs are provided at the above website.

Thanks again,
Johannes Grad
