Applied Parameters: Orientation=3|S=GND|Style=5|Repeat=True
This command is used to place a predefined Signal Ground power port onto the active document. A power port is an electrical design primitive. It is a special schematic object used to define a power or ground net. Power ports allow the designer to conveniently indicate a power net at any location in the design, which can then be connected to pins or wires.
This command is accessed in the Schematic Editor by choosing the Place Signal Ground power port entry, on the Power Sources drop-down () of the Utilities toolbar.
After launching the command, the cursor will change to a cross-hair and you will enter power port placement mode. A power port symbol will appear "floating" on the cursor.
- Position the object and click or press Enter to effect placement.
- Continue placing further power ports, or right-click or press Esc to exit placement mode.
Additional actions that can be performed during placement are:
- Press the Tab key to access the Power Port dialog, from where properties for the power port can be changed on-the-fly.
- Press the Alt key to constrain the direction of movement to the horizontal or vertical axis, depending on the initial direction of movement.
- Press the Spacebar to rotate the power port anti-clockwise or Shift+Spacebar for clockwise rotation. Rotation is in steps of 90°.
- Press the X or Y keys to mirror the power port along the X-axis or Y-axis respectively.
- The graphical symbol selected for a power port does not determine which net it is assigned to. The net name must be explicitly set.
- Power nets of the same name automatically connect throughout the design. There is one exception to this rule, if a Power Port is specifically wired to a Port object then that power net becomes local to that sheet - net connections beyond the sheet must then be defined by the wiring of the Port/Sheet Entry combination.
- While attributes can be modified during placement (Tab to bring up associated properties dialog), bear in mind that these will become the default settings for further placement unless the Permanent option on the Schematic – Default Primitives page of the Preferences dialog is enabled. When this option is enabled, changes made will affect only the object being placed and subsequent objects placed during the same placement session.
