Is there a specific reason why the number of units per symbol is limited to 64?
For some reason all of our schematics at my company treat connector pins as individual units of 1 symbol. This could have just been someone’s preference and the EDA tool used at the time allowed for it. For example I know DxDesigner does this.
We have connectors with 300+ pins. Making a gigantic box with all the pins attached is cumbersome placing it in the schematic and you are essentially forced to use labels to connect everything. I could make it 3 units with 100 pins each or some similar breakdown but to me it’s much easier to just place 1 pin at a time wherever needed.
There are of course pros and cons of this approach, one being connector pins can be placed all over the schematic making locating them difficult. But a pro is if I am not using all X pins I don’t have to place them or use NC symbols.
If the limitation is 64 units per symbol no matter what that is fine I can work around but figured I would check anyways.
