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. Sunay
