gEDA-user: gschem symbols with multiple identical (power) pins?

[Stefan Salewski <mail@xxxxxxxxxxxx>]

Hello,

there exist devices like the OpAmp THS4303 with multiple identical pins
(pins 9,10,11,12 for +V, pins 1,2,3,4 for -V and pins 5,6,7,8 for OpAmp
output signal).

I know that I can divide symbols into multiple parts (i.e. power and
signal), I do this for large parts like FPGAs and ADCs.

But I like to have one single OpAmp symbol with visible power pins --
operation of an OpAmp depends on supply voltage, so it is useful to see
how power pins are connected. (Making 8 power pins makes the symbol very
large and ugly.)

I have decided to make one power pin visible and to connect the other
power pins by a net attribute. gsymcheck is not happy with this
solution, but gsymcheck is not happy with the gnd-1.sym shipped with
gEDA also. Will my solution work, or is there a better way to handle
identical pins?

Best regards

Stefan Salewski

Here is the symbol:
