    Thread Summary
    
                The user inquired about changing COUT and checking PM/GM simultaneously in PowerStudioDesigner. The support engineer explained that in the 'Analyze → Loop and Load Transient' screen, selecting 'Capacitor – Ceramic (Couta1)' or 'Bulk (Coutb1)' reveals the 'Actual Capacitance' field, where entering a value updates the graph automatically. No need to press ENTER, but the update may take a few seconds.

    I can change COUT and check the PM and GM on LTPowerCAD.
    

    I could not find the place to change COUT and check PM/GM at the same time on PowerStudioDesigner.
    

    How can I do that?

      Hello hk22,
      

       
      

      

      

      When you open Capacitor – Ceramic (Couta1) or Bulk (Coutb1) on the left side of the Analyze → Loop and Load Transient screen, the Actual Capacitance field appears.
      

       
      

      When you enter a value there, the graph is updated automatically.
      

       
      

      You do not need to press the ENTER key when entering the value, but it may take a few seconds for the graph to update automatically.
      

       
      

      Regards,
