S-Parameters from Various Input-Output Modes

S-parameter results can be simulated for designs using various combinations of input and output modes. These modes include differential, common, and single-ended. Advanced Design System offers the following component and examples supporting various techniques for working with S-parameters:

• SP_Diff is an instrument control component and is available in the Simulation-Instruments component library. See SP_Diff (Differential-Mode S-Parameters).
• The example project $HPEESOF_DIR/examples/RFIC/Wireline_Application_prj contains the following designs and datasets that demonstrate simulations and mode-conversion equations. See the documentation for this project in Examples > Wireline > Wireline Applications then scroll to "Signal Integrity Simulations".
  • Common Mode Impedance Simulation is demonstrated in the design ckt_common_imp_ML_thick_metal.dsn.
  • Differential Impedance Simulation is demonstrated in the design ckt_diff_imp_ML_thick_metal.dsn.
  • Differential and Common Mode S-Parameter Basics is demonstrated in mixed_mode_basics.dds.
