Hi All,
I am new to SPICE. I hope I can use it to verify the ideas without working on breadboards. Here's my question:
I have code like this:
.Param X64=8 ... Q_Q5 $N_0024 $N_0023 $N0025 PNP8 {x64} ... .Model PNP8 PNP
The problem is my simulator doesn't understand what "Q_Q5 $N_0024 $N_0023 $N0025 PNP8 8" means. I tried my textbook, couldn't find what the last "8" means either. I want rewrite it in a way that my simulator can recognize.
Could someone help?
Thanks in advance, Jeff
Every simulator I know of would recognize that means "Area=" 8
Except I just realized...lose the "x" and the curly brackets.

I am using Protel se 99, pretty old software to capture schematic and design PCB. It has a built in spice simulator. Maybe I need find some other solutions.
Code like this can not be recognized either:
m8 550 550 V- V- nix l=2u w=25u m=26
.model nix nmos(vto=0.75 kp=205.5u rd=1 rs=1 rg=1 rb=1 cgso=4e-9
+cgdo=4e-9 cgbo=16.667e-9 cbs=2.34e-13 cbd=2.34e-13)Faint!

Hello Jeff,
You could use LTspice to run your netlists. I have checked both of your examples and they run in LTspice. Even better you could use LTspice for your schematic too.
LTspice is a free unlimited SPICE simulator from Linear Technology. I assume it's now the mostly used SPICE simulator.
Best regards, Helmut
