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.
