Feature with .model per instance doesn't work #190

Closed georgtree closed 3 months ago

georgtree commented 3 months ago

Hello! The worked previously feature to add individual to instance models doesn't work any more, for example:

name=X3 model=summer@name INOFFS0=0.0 INOFFS1=0.0 KIN0=1.0 KIN1=1.0 KOUT=1.0 OUTOFFS=0.0
device_model=".subckt summer@name in0 in1 out
.param INOFFS0=0.0 INOFFS1=0 
.param KIN0=1.0 KIN1=1.0
.param KOUT=1.0 OUTOFFS=0.0
A1 [in0 in1] out summer
.model summer summer in_offset=[{INOFFS0} {INOFFS1}] 
+ in_gain=[{KIN0} {KIN1}] 
+ out_gain={KOUT} out_offset={OUTOFFS}
.ends summer@name "

generated netlist is:

X3 net2 net3 net4 summer@name INOFFS0=0.0 INOFFS1=0.0 KIN0=1.0 KIN1=1.0 KOUT=1.0 OUTOFFS=0.0
.subckt summerX3 in0 in1 out
.param INOFFS0=0.0 INOFFS1=0
.param KIN0=1.0 KIN1=1.0
.param KOUT=1.0 OUTOFFS=0.0
A1 [in0 in1] out summer
.model summer summer in_offset=[{INOFFS0} {INOFFS1}]
+ in_gain=[{KIN0} {KIN1}]
+ out_gain={KOUT} out_offset={OUTOFFS}
.ends summerX3
**** end user architecture code
.end

Thank you in advance!
