I take it that you have a 25 pin part and a 50 pin part that can be placed in the same location. I would suggest creating one physical with the maximum number of thru-holes. Use the primitives in the logic such as 'partname_con25' which would have 25 visible pins listed as NC. The second primitive would be partname_con50 and define all of the pins. This way there is only 1 physical for two different stuffing options. And only 1 concept symbol that is needed for two different parts. I would be sure to add some indicator in silkscreen so the 25 pin part does not get stuffed at the wrong end. Please let me know if you have any questions. Shirley H.
