Applied Parameters: None
This command is used to place a Sheet Entry object within the bounds of an existing sheet symbol object on the active document. A sheet entry is an electrical design primitive that belongs within a sheet symbol. It is placed within a sheet symbol to designate input/output ports for the symbol. The sheet entries correspond to ports placed in the source schematic sub-sheet that the symbol represents.
Sheet entries are available for placement in the Schematic Editor only by:
- Choosing Place » Sheet Entry from the Schematic Editor main menu.
- Locating and using the Sheet Entry command () on the Active Bar.
- Clicking the button on the Wiring toolbar.
- Right-clicking in the workspace and choosing Place » Sheet Entry from the context menu.
After launching the command, the cursor will change to a cross-hair and you will enter sheet entry placement mode. Placement is made by performing the following sequence of actions:
- Move the sheet entry attached to the cursor over a placed sheet symbol on the schematic document.
- Adjust the position of the sheet entry in relation to an edge of the sheet symbol, then click or press Enter to anchor the sheet entry to the required edge and complete placement.
- Continue placing further sheet entries or right-click or press Esc to exit placement mode.
- When a Sheet Entry is connected to a Signal Harness, the Sheet Entry becomes a Harness object. By default, the Sheet Entry will change color to match the color of the Signal Harness. Disable the option Sheet Entries and Ports use Harness Color on the Schematic - Graphical Editing page of the Preferences dialog to specify your own color for Sheet Entries or to use the default color.
- To negate (include a bar over the top of) a sheet entry name, use one of the following methods:
- Include a backslash character after each character in the name (e.g., E\N\A\B\L\E).
- Enable the Single '\' Negation option on the Schematic - Graphical Editing page of the Preferences dialog, then include one backslash character at the start of the name (e.g., \ENABLE).
- When instantiating multiple channels from the same sheet symbol, certain signals are repeated and sent individually to each instantiated channel. With respect to a sheet entry, a signal is repeated by using the Repeat keyword in the sheet entry's name (e.g., Repeat(Headphone)). The sheet entry is then wired to a bus, which in turn carries the individual signals to their correspondingly instantiated destinations.
- For information on how a placed sheet entry object can be modified graphically directly in the workspace, see Graphical Editing.
- While attributes can be modified during placement (Tab to open the Properties panel), keep in mind that these will become the default settings for further placement unless the Permanent option on the Schematic - Defaults 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.
