Unless I am mistaken, the PINSEQ is reversed in many of the library
diodes.

Spice requires the anode node followed by the cathode node, as
determined by the PINSEQs, (these, I think, are reversed in many of
the diodes in the library.)

Pcb routes on the pin number, (which are correct in most of the diodes
in the library.)

So, if I want a spice simulation of a diode, PINSEQ=1 would be the
anode, and PINSEQ=2 would be the cathode. I think this is the way
gnetlist -g spice-sdb works.

If I want to layout the diode circuit, PINNUMBER=1 would be the
cathode, and PINNUMBER=2 would be the anode, (and the PINLABEL would
be K and A, respectively.) I think this is the way gsch2pcb works.

Am I right?

    Thanks,

    John
