Keysight CoilSys Issues/Bugs

Hello,

I am new to Coilsys in Keysight ADS 2017 and am experiencing some issues with it.

I create the topology of the transformer/inductor I want, using the model composer.

Then the model composer completes it task, running through the various changes in the structure of the topology I have selected.

Then I assume a model is created. I next try to use Synthesis, so that CoilSys can simulate the various devices made in the model.

I find, even though it says a model is created, that when I use Synthesis it doesnt find or see that there is a model and I cannot select the particular device I have created since it doesnt appear under the Synthesis selection, it is just blank even though elsewhere in CoilSys it says the model has been created.

Am I doing something wrong ? Why wont Synthesis "see" the model created ?

Thank you.
