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 hi= gh in this area). I expect the core developers would also like to see some = test cases.

Hello all.<= br>
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 understa= nd single row may be only .model
refdes=3DU?
model =3D ...= .
model-name =3D name

SUBCKT section adds b= y file mechanism:
refdes=3DX?
model-name =3D name
file=3D/fi= le

Why?


Because the way that the spic= e and spice-sdb back ends are implemented, things like this must be impleme= nted as special cases in the code. There are an unlimited number of such ca= ses, but only a few are actually implemented. If you want another, you have= to modify the Scheme code. That's a major motivation for=9Ahttps://github= .com/noqsi/gnet-spice-noqsi.

In the spice-noqsi back end, you define how a symbol is to b= e represented in the SPICE netlist with a spice-prototype attribute. In thi= s 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 i= n the spice-prototype because it contains the "magic" character &= quot;?". I may consider a less crude quoting mechanism in the future.<= /div>

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