As you select the waveports for convergence, you use the Set, Clear, and Clear All buttons in connection with the Entry Selection and Mode Selection settings. These buttons are enabled when the waveport matrix state and selection settings permit them do something. For example, The Clear button is not enabled until there are entries in the waveport matrix to clear and those selections are permitted by the entry selection. The Set button is not enabled unless the available mode selections permit entries to be set.

You can also select individual entries in the waveport matrix by clicking on grid cells. This action displays a dropdown menu that lets you select ON or "-".

3. Specify Entry Selections and Mode Selections as desired and click SET, or click individual waveport cells and select ON.

In the table location corresponding to the selection, the dash in the display is replaced by ON. For example, selecting the first element in the row list and the fourth element in the column list, and then Set Selection places an ON in the first row, fourth column. You can select one entry at a time via the dropdown in the matrix cell, or clear the entire table with the Clear All button. You can also Clear only the entries specified by the Entry and Mode selection settings (such as off-diagonal, higher order).

4. Click OK to close apply the selections and close the dialog.
