Cool, thanks! (May I ask what is "soon" in the gnucap project, a couple
of weeks?)

Which probably doesn't matter, does anything generate netlists with NA,
now that gnucap no longer does?

Gnucap and ngspice agrees. I could possibly try hspice later. I was more
concerned about problems similar to what I had with ngspice: it being
strictly spice3 based, Is parameters greater than 1 aren't adjusted...
iirc. I'm happy to hear gnucap is aiming at full spice2/spice3
compatibility...

;) Thanks.

I'll see what the future holds, and learn a bit more about how circuit
simulations work, and what this feature looks like in e.g. hspice... No
promises whatsoever, but I might just investigate ... in January. (What
is a "long time" in the gnucap project, a couple of years, I'd think?)
