Applied Parameters: Source=UnderCursor
This command is used to place a Specific No ERC directive on a point in the circuit that is already showing a violation. The No ERC object is a design directive that can operate in two modes. In this specific mode, the directive is configured to target and suppress the warning or error conditions causing the violation, while allowing any other warning or error to be detected and reported.
This command is accessed from the Schematic Editor by right-clicking over a violating object in the workspace (highlighted by a wavy colored line) and choosing the Place NoERC to Suppress command, from the context menu.
First, ensure that the cursor is positioned over the required violating object in the main design workspace.
After launching the command, a No ERC directive will appear floating on the cursor, pre-configured to suppress the violation(s). Simply position the cursor at the relevant point of the object, and click, or press Enter, to effect placement.
Additional actions that can be performed during placement – while the No ERC object is still floating on the cursor – are:
- 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.
- 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.
- You can also right-click on a warning/error in the Messages panel, choose the Place Specific NoERC for this violation command, then jump straight to that point in the schematic and place a No ERC directive configured to suppress that warning/error.
- 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 Specific No ERC directive can be quickly switched to be a Generic 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.
