Hi,
I'm reading up on the tutorial of spice simulation and I'm at the part where it is explained how to use an external LTSpice model.
I try to repeat the steps in the tutorial for a TL072 op amp.
https://oshwlab.com/Zoldar71/create-spice-model-of-tl072
When running the simulation I get the following error 'The circuit has components without simulation model: dx'.
I pasted the AD817 spice model text from the tutorial example in the schema and changed the op amp symbol name to AD817. Now the simulation runs fine.
I can see that the TL072 subckt uses a dx model, but the AD817 subckt also uses a dx model. What am I overlooking?
Cheers,
Martin
Sorry but I cannot reproduce your problem.
If I make a copy of your simulation schematic:
and then:
rename the TL072 symbol to AD817 and then;
set the TL072 subckt to Comment;
set the AD817 netlist to Spice;
or:
rename the TL072 symbol to AD817 and then;
set the TL072 and AD817 subckts to Comment;
or:
rename the TL072 symbol to AD817 and then;
delete both the TL072 and AD817 netlists
then the sim runs fine.
There is already a copy of it in the EasyEDA (and not the LTspice built-in) library.
