    Performing frequency analysis in Hyperlynx SI




      I have a circuit with s-parameter models and i need to perform a frequency domain analysis in certain points of the circuit. I'm using hyperlynx 8.2. When i try to use the spectrum analyser i have the following error message:


      "One or more SPICE models are assigned to the selected net.

      The spectrum analyser currently does not support SPICE modeling.



      I have this error whether i have a SPICE or an IBIS voltage source to my circuit.

      Is there a way to observe the frequency response of my circuit? Or Hyperlynx SI is limited to time-domain analysis when including S-parameter models?
