I am simulating a pulse generator using step recovery diodes. Thre is no step-recovery diode model in ADS. Therefore, I am trying to use the spice paramaters in the Diode_Model of the Component. I can change the parameters, however I cannot physically wire the component in the circuit. I read through the ADS help files but I end up more confused. It seems to be a complicated process to use these models. I would appreciate some help on this subject. Thanks.
In ADS, non-linear devices such as diodes, BJT's, FET's, etc., are implemented as a component with pins, and an associated model card containing the full set of component parameters. This is a common simulator practice.
It sounds like you've got your model card set up the way you want it, but you now need to insert a diode component into the schematic and wire it up. Then have the diode component point to the model by name.
The palette icon for your component will be right next to the icon for the model.
Take a look at the example in:
%ADSroot%/examples/Training/AdvCkt/NOISE_prj
Open any of the three schematic designs, and you will see a good example of this approach.
Notice that the component has a parameter labeled "Model=some_name". And that there is also an associated model card for the component, whose instance name (in dark blue) matches "some_name".
I hope this is helpful information for you.
