Applied Parameters: SymbolType=Device Sheet|InteractiveCreate=True|InteractivePlace=True
This command is used to place a Device Sheet Symbol object onto the active document. Device Sheets are building blocks developed with the intent of being re-used in different designs. They usually contain predefined circuits that are commonly used between projects. Device Sheets are stored as normal Schematic Documents in special Device Sheet Folders. They are placed and referenced in your project similarly to a simple component. When the project is compiled, Device Sheets are included in the project hierarchy.
This command can be accessed from the Schematic Editor by:
- Choosing the Place » Device Sheet Symbol command from the main menus.
- Locating and using the Device Sheet Symbol command () on the Active Bar.
- Clicking the button on the Wiring toolbar.
- Right-clicking in the workspace then choosing the Place » Device Sheet Symbol command from the context menu.
First, ensure that the schematic document on which you want to place the device sheet symbol is the active document in the main design window.
After launching the command, the Select Device Sheet dialog will open. This dialog lists all device sheet folders that have been declared to the software and all device sheets contained therein.
Select the device sheet required then click OK - the corresponding device sheet symbol for that chosen device sheet will appear floating on the cursor. Position the symbol as required then click or press Enter to effect placement. The device sheet symbol will have the correct file name to link it to the child device sheet and will have sheet entries to match each of the ports on that sheet.
Additional actions that can be performed during placement – while the device sheet symbol is still floating on the cursor – are:
- 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 device sheet symbol counterclockwise or Shift+Spacebar for clockwise rotation. Rotation is in increments of 90°.
- Press the X or Y keys to mirror the device sheet symbol along the X-axis or Y-axis respectively.
- After a device sheet symbol has been placed in a schematic document, it will act in the same way as a standard sheet symbol, but has different graphical properties to distinguish that it references a Device Sheet. Note that the File Name property for a Device Sheet does not use the .SchDoc file extension.
- Be sure to compile your project. Upon compilation, all referenced device sheets will be added to your project tree in the Projects panel. You will notice in the panel that device sheet entries have a different document icon () than normal schematic documents (). This distinguishes them as being referenced sheets rather than sheets explicitly added to your project.
- Device sheet folders can also be managed from the Data Management - Device Sheets page of the Preferences dialog. This page also provides additional options, such as controlling whether or not editing of device sheets is allowed (typically a device sheet would be edited outside of the project it is used, and therefore kept Read-Only when brought into a project).
- 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.
