Applied Parameters: SuppressAll=True|Repeat=True
Summary
This command is used to place a Generic (or non-specific) No ERC object onto the current document. The No ERC object is a design directive that can operate in two modes. In this generic mode, the directive is placed on a node in the circuit to suppress all reported Electrical Rule Check warnings and/or error violation conditions that are detected when the schematic project is compiled. Use this directive to deliberately limit error checking at a certain point in the circuit that you know will generate a warning (such as an unconnected pin), while still performing a comprehensive check of the rest of the circuit.
For detailed information about this object type, see
No ERC.
Access
This command can be accessed from the Schematic Editor by:
- Choosing the Place » Directives » Generic No ERC command from the main menus.
- Locating and using the Generic No ERC command () on the Active Bar.
If the command has been recently used from the Active Bar, it will become the active/visible button. Where other commands are available, this is indicated by a triangle at the bottom-right corner of the button. Click and hold on the active button to access a menu of all associated commands for that grouping.
- Clicking the button on the Wiring toolbar.
- Right-clicking in the workspace and choosing the Place » Directives » Generic No ERC command from the context menu.
Use
After launching the command, the cursor will change to a cross-hair and you will enter placement mode. The graphic for the No ERC object will appear floating on the cursor. Simply position the cursor over a wire or other net object, and click, or press Enter, to place a directive at that point in the circuit.
Continue placing further Generic No ERC directives, or right-click, or press Esc, to exit placement mode.
At any time during placement, press the
Tab key to access the
Properties panel, from where properties for the No ERC can be changed on-the-fly. Pressing
Tab pauses placement, allowing you to interact with the panel (or other area of the software) directly. To resume, click the pause symbol that appears over the workspace, or press
Esc.
Additional actions that can be performed during placement – while the No ERC object is still floating on the cursor – are:
- Press the Spacebar to rotate the No ERC object counterclockwise or Shift+Spacebar for clockwise rotation. Rotation is in steps of 90°.
- Press the X or Y keys to mirror the No ERC object along the X-axis or Y-axis respectively.
Tips
- Rather than deleting a No ERC directive, it can be simply made inactive (disabled in the eyes of the Compiler). This state can changed by toggling the directive's Active property - either through the Properties panel (when viewing the properties for a selected No ERC object), or the SCH List panel.
- A Generic No ERC directive can be quickly switched to be a Specific No ERC directive, either through the Properties panel (in the Suppressed Violations section), or by toggling the Suppress Specific Violations property, on the SCH List panel.
- Suppressed violations can be displayed on the Messages panel by enabling the Report Suppressed Errors in Messages Panel option, on the Error Reporting tab of the Options for Project dialog. This feature can be used in the final stages of design to ensure that no critical errors have been inadvertently suppressed.
- By default, all design directives are included during printing. To control this, disable directives that you do not want included on your printouts in the Schematic Print Properties dialog.
- While attributes can be modified during placement (Tab to bring up the Properties panel), bear 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.
