Hi
I ma trying to re simulate an extracted design and getting strange results. It is acting as if all the inputs and outputs of sub blocks are floating and their is no interconnection between sub blocks.

Background:
I have tried extract and simulate one level say an inverter and it works fine but when I try a higher level design say two inverters back to back it acts as if they are not connected. I did get it to extract and simulate properly when I do c only but fails when you add r parasitic exaction.

One form I found said to try
setenv DBGRCX_CONNECTIVITY Y
and run Icfb.

With this set I get the flowing error when I try and extract r parasitics:

cat <<ENDCAT> gemfilterfile
F model=C 2 X X
ENDCAT
gemini -V -S -w -td 0.01 -flt gemfilterfile -ac"C" -prr_c '#' -f_name_io \
s#vdbToRcx.sp s#/data1/jmoore/lvs/test1/extview.tmp

ixed.

This problem started after upgrading our design kit and Assura.
we are using IBM: cmrf8sf V1.7.0.2DM or V1.8.0.1DM/ (fails with booth)
Assura (tm) Physical Verification Version av4.1:production:dfII6.1.3:IC6.1.3.500.10
Cadence Extraction QRC - Parasitic Extractor - Version 9.1.4-p008 Thu Nov
 

I up graded all soft ware to latest release we have a license for and and it works.
