How can I read Smith Chart in Virtuoso?

StillLearning
Hello everyone,

I am confused with the Smith Chart that Cadence’s Virtuoso plots. I have never seen such a representation of Smith chart over the past 20 years of my familiarity with and use of paper-based Smith Chart.

Could someone help me with reading Virtuoso’s Smith Chart? I need to make a correspondence between the paper-based Smith Chart and that displayed by Virtuoso. For example, where is the Center of Virtuoso’s Smith Chart? There is no correspondence at all between the two.

Thank you in advance for your attention and guidance.
 

Still Learning.

  • Hi Still Learning,
     
    You may have run into a bug.  Please file a Service Request.
    I am in a class right now, so I cannot dive deeply into this, unfortunately.
    There is also a known bug with the Smith Chart that was just fixed in the
    latest ISR of IC6.1.4 and also in IC 6.1.5.  The Smith Chart is
    MUCH better in IC 6.1.5.
     
    We are also improving the documentation - I completely agree that
    it needs work.
     
    I am very interested in hearing more about how you would like the Smith Chart
    improved.  (I am sitting next to the Product Engineer for ViVA in this class.)
    Please email me off-line and we can continue our discussion further.
     
     
    Best regards,
