Assura RCX

[Sunay]

Am using Assura RCX to extract cap parasitics. Extraction of
sub-blocks of the circuit work fine ( Extract to Avextract view).
When I attempt to extract the top block I get the following error
message:

*WARNING* /home/cadsw/cad/cadence/v4.4.6-assura/tools/assura/bin/rcxToDfII
exit
with bad status
*WARNING* Segmentation Fault
*WARNING* Assura execution terminated

This error does not occur when I extract to a Spice file.

Thanks for your help in advance.
