Ground Ports

A ground port serves as a connection to the reference or ground node, node 0 in Twin Builder circuit designs. Ground ports cannot be renamed.

To place a ground:

1. Select the schematic that will contain it.
2. On the Schematic ribbon, click the Ground icon . Alternatively, click Ground on the Draw drop-down list.

The cursor, carrying a ground symbol for placement, can be moved to the schematic window.

3. To place a ground, click the desired location on the schematic.
   Note:

   You can rotate a ground before placing it by repeatedly pressing R on your keyboard. Each press rotates the ground 90º counterclockwise. After placement use Ctrl+R to rotate the ground.

Twin Builder supports multi-domain grounds for conservative pins and nets. Based on the type of net connection, Twin Builder changes to the appropriate ground symbol and net (wire) color. For example, the net (wire) color for hydraulic connections is green and the default hydraulic ground symbol is .

If two domains are merged on a common ground, the net connection defaults to the normal blue color and the default ground symbol .

Net connection colors and ground symbols revert to the appropriate states when the merged domains are separated by deleting the connecting wires.

If Multiple Placement is turned on for grounds in the Schematic Options dialog box, click additional locations to place additional grounds.

To stop placing grounds during multiple placement, do either of the following:

• Press Enter, the SPACEBAR, Backspace, or Esc on your keyboard.
• Right-click and select Place and Finish, Finish, Cancel, or Back.
  Note:

  To ensure electrical connectivity among schematic elements, the pins of placed grounds snap to a 100-mil (2.54-millimeter) grid. This snapping cannot be turned off, and the spacing of the connectivity grid cannot be adjusted.
