Hi, I have created an AMP and when I am runing the sim I am getting the following error. Can someone help me out? I am using xschem with ngspice.

@Praveen raj Does adding an

X

before the

AMP1

on line 3 make a difference?

Thanks. It helped. So, all the instance name should start with X?

Yes. That’s SPICE syntax. Subcircuit instances start with

X

, mosfets start with

M

, diodes start with

D

, resistors start with

R

, capacitors start with

C

, inductors start with

L

and bipolar transistors start with

Q

.

Okay. Thanks
