    Differential pair simulation

    ishara0925

      Hi all,

       

      When I try to simulate a differential pair (from IC to a pair of SMA connectors) , it generates the following error. In the assigned ibis model pins are defined as differential. What could be the cause for this?

       

      No differential twin pin foundNo differential twin pin found

       

      Thank you

          For your IC IBIS model, check that the [Diff Pin] is defined. Then for your SMA connector, create a dummy IBIS model with the same diff pin net names.

          In HyperLynx, when you select the net, you may still need to define which is 'Output' and 'Output Inverted'.

          The simulation should run now.

          Alternatively, you can define net pairs under Setup > Differential Pairs
