Creating component from a working model causes convergencie problem


Started from the OPAMP_5T_VIRTUAL (in Master Database) I built a model and modified it at some points. My aim was a parametric OpAmp which can be saved with a given name after setting the parameters.

There are OpAmps which have no SPICE model in the database but the OPAMP_5T_VIRTUAL cannot be saved into the User Database with specific settings.


The model perfectly works with all its built-in limitations.

After the testing I created a user component ParametricOpAmp with the model script (based on the net-list of the model). The component is absolutely the same as the schematic of model (I checked it repeatedly).


Testing the new component it immediately causes a convergencie problem and nor the Multisim, nor me cannot resolve the problem.

If somebody can discover the reason, please help me.

It was a false alarm. Somehow there was a duplicated part in the component model. I didn't notice it.

Excuse me...
