When creating a schematic symbol, how to pre-connect pins?
« on: December 24, 2014, 08:50:49 pm »
I have a regulator with 3 terminals. The case is a standard SO8 package and I would like to create a symbol that only shows those 3 pins.
2 pins in the case are unconnected - how can I set this at the schematic symbol library? And 4 of the remaining pins are all shorted together, how can I define that to be done automatically also in the schematic symbol library?

Maybe not desirable to do it 'inside' the schematic symbol, as the connections should be obvious to anyone viewing the schematic - without having to look for the part's datasheet.
Don't ask a question if you aren't willing to listen to the answer.

NEVER do that !

The unconnected pins you simply dont need to define.
The others that belo g together you neatly place next to each other. So you can wire them easily on the schematic.

There are people that draw pins on top of each other. The effect is a schematic with hidden pins. That is an absolute nightmare ! A schematics putpose is to show ALL connections.
