m parameter in lv_mos models of Xyce in the current dev-branch dont work

[olisnr]

to demonstrate it, i added two transistors to the ihp-sg13g2/libs.tech/xschem/sg13g2_tests_xyce/ac_lv_nmosrf.sch. one with m=10 and the other with w=10u (standard is 1u).

i would expect similar results, but the m=10 device looks exactly like the m=1 device with the same w...

ac_lv_nmosrf_mult_Xyce.sch.zip

my simulation command is Xyce -plugin $env(PDK_ROOT)/$env(PDK)/libs.tech/xyce/plugins/Xyce_Plugin_PSP103_VA.so "$N"

I can confirm that multiplier didn't work with Xyce. It seems that Xyce can not change parameter "m" in subckt call.
Changing this parameter name to "mult" or something else will work as in following script:

`psp103 nch transfer

vd d 0 dc 0.1
vg g 0 dc 0.0
vb b 0 dc 0.0
XPSP103_VA d g 0 b psp_sub w=10u l=1u mult=2

.subckt psp_sub d g s b w=10u l=1u mult=1
YPSP103_VA m1 d g s b nch l='l' w='w' mult='mult'
.ends

.option temp=21
.step vb -3 0 0.5
.dc vg 0 1.5 0.02
.print dc format=gnuplot v(g) i(vd)

.model nch psp103_va type=1

.end
`

Xyce team has agreed that the parser has a bug.
Change parameter name to mult instead m for symbols and subckt definitions for xyce and ngspice lib's is preferable. Positive side effect is that the meaning for the user is unique.
