Viewing Matrix Data in 2D Extractor

You can view matrices computed for resistance, inductance, and capacitance during each adaptive or non-adaptive solution:

  1. Access the Solutions window one of two ways:
    • In the project tree, under Analysis, right-click the solution setup.
    • The right-click menu appears.

      Analysis > Setup Right-Click Menu

      Select Matrix...

    • Or, from the ribbon, click Results > Solution Data.
    • Solution Data Icon

     

    The Solutions window appears, with the Matrix tab selected.

    Solutions Window > Matrix > View

  2. In the Design Variation text box, set the design variation by clicking the ellipses (...) icon.
  3. The Set Design Variation window appears, listing all solved variations in the design.

    Set Design Variation

    Note:

    You can also access this window from the project tree by right-clicking Results and selecting Apply Solved Variation.

  4. From the Simulation drop-down menus, you can select setups and either adaptive or sweep solutions. Select the solution and type of matrix you want to view (CG, DC RL, or AC RL). Available types differ based on the solution type.
  5. The Matrix tab contains four sub-tabs: View, Format, Passivity, and Export. The View tab displays by default.
  6. From the View tab:

    • Select the Units in which to display matrix information. Available units depend on the matrix type.
    • The units are saved in the matrix panel. Units are stored only for the current session and current project. Changing the units in a project does not affect the units in another project open at the same time. Closing the project resets the units, and changes are lost.

    • Use the drop-down menus to select reduced matrices to display. Choices include Coupling Coefficient, Maxwell Matrix, and Spice Matrix. Maxwell Matrix and Spice Matrix are only available in the Capacitance matrix. By default, the Original solved matrix displays.
    • Matrix Selection           Original Matrix Selection

    • To show matrix entities for reduced operations, click the Original menu and select Reduced matrices.
    • Select the solved frequencies to display using the provided options:
      • Frequency Drop-Down Menu – allows you to select the frequency for which you want to view matrix entries.
      • All Freqs – allows you to display matrix entries for all solved frequencies.
      • Pass – for an Adaptive Pass, allows you to select the pass for which you want to view matrix entries.
      • Edit Freqs – for an Interpolating Sweep, opens the Edit Sweep window, allowing you to insert or delete displayed frequencies.
    • Use the Self Terms check box to display only the diagonal of the selected matrix.
  7. Click the Format tab.
  8. The Format tab displays, with additional options.

    Solutions Window > Matrix > Format

    From the Format tab:

    • Select either the Default or Custom display.
    • If you select Custom, specify the matrix field Width and Precision in digits.
    • Select the Use Scientific check box to display matrix data using scientific notation.
  9. Click the Passivity tab.
  10. The Passivity tab displays.

    Solutions Window > Matrix > Passivity

    From the Passivity tab:

    • Set the Passivity Tolerance.
    • Click Check Passivity to check passivity under the specified Passivity Tolerance.
    • An alert appears, showing the result.

      Passivity Alert

    • Click OK to close the alert.
  11. Click the Export tab.
  12. The Export tab displays.

    Solutions Window > Matrix > Export

    From the Export tab:

    • To export matrix data, click Export and select either RLGC or S Parameters from the drop-down menu that appears.
    • Export Drop-Down Menu

      The Export Matrix window appears.

      Export Matrix Window

      Select your desired options and click Save.

    • To export the equivalent circuit, click Equivalent Circuit Export.
    • Note:

      You can only export the current problem type, and will receive an error message if you try to export both CG and RL.

  13. Click Close to exit the Solutions window.
  14. Note:

    Selections in the Solutions window persist during execution, but are reset to their defaults on exit.
