Morris - Thanks for your post; my apologies for the delayed response. The notification system for the Communities has been experiencing some issues.
I am going to move this to the appropriate PADS community where it will receive greater visibility by PADS users. This area is for general community questions and suggestions.
You are correct in your findings, the underlying structure of the part in the integrated flow is different to the netlist flow, the machinations of what is really being used is hidden from the user behind the PADS Part Editor. In VX.2.4 the tools will switch to using the native Central Library Part Editor (same as in PADS Professional) where this column is no longer exposed (or used) and will hopefully avoid this kind of confusion.
Thanks for the reply. It’s good to know my parts will not cause problems due to pin sequence numbers.
