I'm trying to probe the transient voltage of an internal node in post layout simulation without creating an explicit port on my top level. I used Calibre for PEX. I tried to use the "Map Schematic Nets to CalibreView Net" in ADE L's Calibre drop down menu to find the post layout net name of the node I want to probe on schematic level, but when I click on it the CDS.log shows "extviews.txt is not a file". It seems that normally another window should pop up and once I select the node on my schematic, it will show the post layout net name of the node. Can someone help me debug this? Thank you so much in advance
