Hello, I tested a little bit, so now I have a question: why these almost identical subcircuits gives the different results?
This works good:
VDS2 N001 0 0 Rser=0
VGS N002 0 {vgs}
X3 N001 N002 0 tj tj mos_hv
VGS1 tj 0 {temp_v}
.step param vgs list 1 2 3 4 5 6
.param nmos_vds=1
.dc vds2 0 5 0.01
.param temp_v=25
.subckt mos_hv d g s tj tmb
M1 d g s s tj nmos_hv l=0.28u w=1
.ends mos_hv
.model nmos_hv nmos(level=73 xldld=0 coselfheat=1 RTH0=1e12)
.backanno
.end
This doesn't work:

.end
The only difference is different pin names, I changed tj to t1, t1 is different from name of pin name inside subcircuit, and it creates problem.
But I thought that only pin order matters, not name of node inside of subcircuit, its name should be invisible to outside circuit, but seems it doesn't work this way.

I suppose that there is some problem with 5-node mosfet model, because by default MOS models have 4-pin.
But sometimes it works, so maybe it is a bug?
Thank you in advance.
