Even if you don't use the power symbol, you still have to distribute the refdes strings of slotted symbols manually. gschem has no way to know which symbols you intend to put in the same package. Yes, some kind of heuristics may be imaginable. Ideas have been floating on the mailing list.

First I manually set the ”device=” to match existing components, then I added ”numslots=” to match. IN some cases it's 4 and in some cases 6 (NOT gates for example), but no matter what I did it was numbered wrong, with a higher number than the existing components. What am I missing? Should I edit the symbol itself or should I set something in the schema or what?

Well, I am sure which pin is what, I am not sure I got it right in my symbol though, but I can test it, don't worry… :) For pin type you may simple use "pas" for passive, as in resistors. The default 4066 symbol used ”pas” for the switch thing and ”in” for the ”enable” thing. I guess I'll do the same then, since some people already suggested that.

A single 74_pwr.sym can not work for 14 and 16 pin parts, so I really recommend to do not use a 74_pwr.sym at all, but one for 14, and one for 16 pins devices. I think I called my one at gedasymbols 74xx-14N-Pwr-1.sym. Does the 74-series version differ in layout from 4066? May be. >I am not sure I got the pin numbers right (or how to use pinseq vs >pinnumber). It may be better to be sure. For pin type you may simple use "pas" for passive, as in resistors. ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

I created this symbol, it's the 74-series version of the 4066 (4 bilateral
switches), called 744066 (as in 74LV4066, for example):

The documentation of the symbol can be found at
http://focus.ti.com/lit/ds/symlink/sn74lv4066a.pdf
I am not sure I got the pin numbers right (or how to use pinseq vs
pinnumber).
I am also not sure about the pin type of ICs like this one. It's not
really just ”in” and ”out”, is it? I used ”in” and ”out” anyway, since I
couldn't come up with anything better, and I called the third one ”en” as
in ”enable” but I am not sure about that one either. This is maybe not a
symbol question but rather a question about the IC itself, so maybe this
is way off topic…
Suggestions?
