I've read the gschem documentation (only) enough to read the part that
says "buses are still very experimental". Nevertheless, I thought I
would give it a try. I have a symbol that I've imported has a bunch
o' pins labeled:
EM_A[0]
EM_A[1]
EM_A[2]
...
So I drew a bus down along side of the sym

The losses do not agree with the mfg datasheet.
A problem with the LTRA model here is that it doesn't account for

Thanks for the replies.
I have not looked into this type analysis for some 20 years. I still
have my Terman reference!
The value/unit is specified in the Spice 3f5 help pages.
I used the value/foot specifications for Belden 9914 Coax and

Odd, mine apparently makes the same mistake - except that I've hacked
my system to have a symlink in the right place :-P
$ ls -l /usr/include/Xm

I'll see what I can do about it.
