Here's another take on the options we have now: When you have need for some gates
less than a word width use tiny logic packaged in 4 or 6 or 8 pin packages and do not
create slots in the symbols at all, and get the benefit of less spaghetti wiring going
hither and yon. When you want 8 or 16
Is there anyway in gschem to have a list of descriptions per pin and then just
select which one must be shown?
e.g.
On a PIC16F628A pin 12 alone has four different functions :
RB6, T1OSO, T1CKI, and PGC
When I try to add all the pin descriptions to a PIC microcontroller it ends up
having to be a

I think even a normal TTL gate generates noise on the top of the power

Just have a separate page that has nothing but power connections on it.
Problem solved. This is a very common practice.

Taking a 7400 as an example, you would have five ga
1) Implicit connections are good when they help minimize the crowding of
a schematic.
2) Others who then look at the schematic often ask where is the power

conventionally shapped chips)

We made a new library here. We use to have the integrated circuit in one
symbol and one symbol with only the power pins. Both must have the same name,
like U1. To me, it is simple to draw, makes the design clean and with a
consistent netlist.
