Using Reduce Matrix > Float Terminal

The Float Terminal operation allows you to "turn off" the current in a particular source terminal. The effect on the inductance and resistance (IR) matrices is to eliminate the row and column associated with the selected source terminal. The other entries of the matrix are unaffected.

To float a source terminal:

1. Click Q3D Extractor > Reduce Matrix > Float Terminal.

   The Reduce Matrix - Float Terminal window appears, with a list of terminals in the left pane.

   

2. Select the terminal(s) you want to float. As soon as you click a terminal, it is removed from the terminal list and added to the Reduced Net List.
   Important:

   You cannot select all source terminals.

3. If you have a long list of terminals, you can filter the list by entering search criteria and clicking Filter. Use multiple search criteria with a comma separator (for example, "Redsource*, BlueSource*").
4. Click one of the following:
   • Save and Create to save and leave the Reduce Operation window open to add an additional operation. You must select the next operation from the drop-down menu before clicking this button.
   • Save and Close to save the current operation and close the window.
   • Cancel to close the window without making changes.
