Imported model sim

Hi,

I imported a model and created a library for OPA855 from the official website however when I am trying to check the operation of the reference circuit the simulator simply doesn’t run. I also don’t get any errors.

Any idea how to fix this?

It did return an error.

You added the 2nd and 3rd string attributes V+ and V- to describe the Vcc and Vss pins, but you did not mark them as comments. As a result, they will become text strings that follow the OPA855 model name in the netlist, and these extra characters cannot be recognized in the netlist and therefore return error.

You have to mark every description text as a comment in a symbol.

Normally, it is suggested to use Pin Labels. Pin labels will not be interpreted in the netlist. You can name the pin whatever you want! Pin labels do not affect the matching of the .subckt. The matching always follows the Pin Order between the symbol and its .subckt.

Beware that your symbol pin order does not match your .subckt pin order. The pins will be matched incorrectly; currently, Vcc is connected to OUT, Vss is connected to Vcc, and OUT is connected to Vee. If you are new to symbol creation, remember not to change the pin order or the name of the pin label (as you will think the name to match but it is not), or you could end up confusing yourself.
