If you are attending the International Microwave Symposium (IMS 2013) in Seattle (June 2-7, 2013) stop by the Cadence Design Systems booth, #427.

We will be showing new MMSIM12.1.1 features including

  • “Smart” HB GUI,
  • Robust and easy to use nport (for s-parameter input), and the
  • Transmission Line library workshop.

Looking forward to seeing you!

Best regards,

Hello Twanal/Cadence Support,
  ( I am not sure if this is the right place to put my question, but i have been struggling with this problem since one week and i need to solve it quickly).     I am having the problem figuring out how to run IP3 simulation if the input file is a pwl file. I am easily able to run all other analysis of PSS except the IP3. I have tried PSS+PAC, QPSS which are usual for calculating IP3 but it dont work. For example,with the PSS+PAC analysis the PAC>IPN Curves has the message ''The data for each sideband of the pac analysis contains are frequency sweep.As a result,the above selected function cannot be executed'. Is there any way to simulate get the correct IP3 with the 3rd order intermodulation distortion curve if the input singla is in pwl format. it seems a easy thing to do, but i have tried all i knew and asked my colleagues but nobody has able to figure it how to do it?
I need urgent help in this regard!

Hi Tawna ,I am working in 20nm technology .i have design a LNA but PSS,Sp,PAC curves are not getting only the simulation has run but all the curves cannot be plotted only gain has plotted rest of not getting.please help me.
