Well, I haven't pushed for it = to be. I'm not happy with the lack of documentation (Stuart Brorson has = set the standard very high in this area). I expect the core developers = would also like to see some test cases.

Thank = you John.

This is works even = with ? characters :)))

Hello= all.
I want to place to symbol single row model .subckt.

Example of spice:

.SUBCKT opamp 1 2 3 4 5
B1 5 = 0 V =3D V(3)<1e5*(V(1)-V(2)) ? V(3) : V(4)>1e5*(V(1)-V(2)) ? V(4) = : 1e5*(V(1)-V(2))
.ends

But I do not finded this in wiki.
How I = understand single row may be only = .model
refdes=3DU?
model =3D = ....
model-name =3D name

SUBCKT section = adds by file mechanism:
refdes=3DX?
model-name =3D = name
file=3D/file

Why?


Because the way that the = spice and spice-sdb back ends are implemented, things like this must be = implemented as special cases in the code. There are an unlimited number = of such cases, but only a few are actually implemented. If you want = another, you have to modify the Scheme code. That's a major motivation = for https://github.com/noqsi/gnet-spice-noqsi.

In the spice-noqsi back end, you define how a symbol is = to be represented in the SPICE netlist with a spice-prototype attribute. = In this case (assuming your symbol has pinseq attributes in the correct = order for the other back ends), you could use two multi-line = attributes:

spice-prototype=3DX? %pinseq = opamp
model@

model=3D.SUBCKT opamp 1 = 2 3 4 5

B1 5 0 V =3D V(3)<1e5*(V(1)-V(2)) ? V(3) : = V(4)>1e5*(V(1)-V(2)) ? V(4) : 1e5*(V(1)-V(2))
.ends

You can't put the model directly in = the spice-prototype because it contains the "magic" character "?". I may = consider a less crude quoting mechanism in the future.

You can also use pin number to specify connections = in any order if pinseq isn't right: this gives you a way around the = overloading of pinseq (also used for slotting). spice-noqsi can also = imitate the way gnetlist natively handles hierarchy when flattening a = netlist, allowing you to create hierarchical SPICE netlists representing = circuits drawn for flat printed circuit designs.
