Viewing Mode Data

The 2D Extractor computes distributed values of capacitance and inductance along the length of each line, which would require a ladder network model consisting of a large number of inductances and capacitances. To model the transmission line, the software uses modal transformation matrices to transform an n-conductor coupled line into an n-mode decoupled line, where each mode can be visualized as a specific pattern of voltages on the physical conductors.

To view Mode Data, either during or after the solution process:

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.



Select Mode Data...

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



Select the Mode Data tab.

The Solutions window appears, on the Mode Data tab.



2. The Mode Data tab contains three sub-tabs: View, Format, and Export. The View tab displays by default.

From the View tab:

• Use the drop-down menu to choose from Original or Reduced matrices.



• Use the drop-down menu to select a frequency, or select the All Freqs check box.
• Click View Options to open the Set View Options window.



• From this window, you can set Matrix Visibility for Modal Characteristic Impedance and Propagation Velocities, as well as preferred units of measurement.
• Click OK to apply changes.
Note:  

Selections persist during execution, but are reset to their defaults on exit.

3. Click the Format tab.

The Format tab displays, with additional options.



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 Mode data using scientific notation.
4. Click the Export tab.

The Export tab displays.



From the Export tab:

• To export Mode data, click Export.

The Export Matrix window appears.



• Select your desired options and click Save.
5. Click Close to exit the Solutions window.
