POLY in ng-spice

[habib bouaziz-viallet]

Hi all,

POLY() sources constructions does not work from within ng-spice even
spice3f5.

Any method to fix it ?

Thanks, Habib

Please post your troublesome netlist and an accompanying session log.

Also, which version of ngspice are you using?

The MacSpice transplation of the polys() is:
===============================================================
MacSpice 5 -> source Test

Circuit: test

Note -- MacSpice converts spice2 'polys' to spice3 'B' sources,
use 'listing physical expand' to inspect the result(s).
Note -- Line 2 spice2 'poly' source converted.
Note -- Line 3 spice2 'poly' source converted.
MacSpice 6 -> listing physical expand
test

1 : test
2 : *egnd 99 0 poly(2) (3,0) (4,0) 0 .5 .5
2 : bsp2_egnd 99 0 v=(0+v(3)*.5+v(4)*.5)
3 : *fb 7 99 poly(5) vb vc ve vlp vln 0 7e6 -1e3 1e3 6e6 -6e6
3 : bsp2_fb 7 99 i=(0+i(vb)*7e6+i(vc)*(-1e3)+i(ve)*1e3+i(vlp)*6e6+i(vln)*(-6e6))
------ : .end
MacSpice 7 -
===============================================================

I suspect that the problem with ngspice is caused by using (,) as
separators which which confuse the ngspice tokeniser into thinking that
(3,0) is a single token. Try instead:

egnd 99 0 poly(2) 3 0 4 0 0 .5 .5

Thanks Charles,

This very .cir description works well with spice-opus
http://www.fe.uni-lj.si/spice/welcome.html

and not (for the moment) with ng-spice 1.5. May be Xspice extensions not
may not work with ... it's very surprising, mmmh...!

I suspect that the problem with ngspice is caused by using (,) as
