How can I build my own IC lib. I would like to use the OPA380 OP-AMP, so do you have a model lib. for it.

Have you seen this in the FAQ?

That's the best you can do in CL at present but it should be OK for many applications.

Note that the OPA380 is not an opamp, it's a transimpedance amplifier.

However, you can model it using CL opamps from the simplified diagram on the front sheet of:

Or you can model it using a behavioural voltage source to control the output voltage from an input current (transimpedance = Vout/Iin)
