I know through the years there has been a lot of
discussion on this issue but I haven't been able to find the answer to my
problem after searching the archives. I'm wondering how to refer to a 3
pin footprint with a two pin schematic symbol as is the case for a sot23
diode. My actual question is probably simple for the experts out
there. I've already created a special symbol for a sot23 diode. The
actual symbol graphic is a normal diode that has 2 pins, pin 1 and pin3. I
believe I need to specify a pin 2 in the symbol textually somehow so that PCB
layout software will match its 3 pin footprint to a schematically defined 3 pin
device. How do I annotate the gschem symbol for a pin 2 without a
graphical entity to assign the pin to. It's a no connect or unused pin so
it needs no graphic but the symbol does need to have 3 pins when the netlist is
generated for layout.
Thanks
Ed
