Whether validating a project, running a design rule check for the active PCB document, performing a mixed signal simulation, or using any of the other message-enabled features of the software, the Messages panel provides an intelligent way of listing any warnings and/or errors that may be present, as well as any status information. 

Click here for information regarding possible violations when a project is automatically compiled. 

Panel Access

The Messages panel can be accessed in the following ways:

  • Click the Panels button at the bottom-right of the workspace and select Messages.
  • Choose View »  Panels » Messages from the main menus.

Content and Use

The Messages panel includes the results of project compilation and lists any warnings and/or errors that the Compiler may have found while checking the design for electrical and drafting integrity.

The design connectivity model is incrementally updated after each user operation through dynamic compilation. You do not need to manually compile the project, as this is done automatically. For a design project, the automatic compilation process performs three functions:

  1. Instantiates the design hierarchy.
  2. Establishes net connectivity between all the design sheets.
  3. Builds an internal Unified Data Model (UDM) of the design.

In order to check for logical, electrical, and drafting errors between the UDM and compiler settings, you must validate the project. This command is accessed by choosing the Project » Validate Project command from the main menus or by right-clicking over the entry for a project in the Projects panel, and choosing the Validate Project command from the context menu.  

Any violations that are detected by the Compiler will be listed as warnings and/or errors in the Messages panel. The Compiler uses the options defined on the Error Reporting and Connection Matrix tabs of the Options for Project dialog (as applicable to the project type), when checking the source documents for violations.

The Messages panel also provides warning/error/status information for many other features in the software. These include DRC, Signal Integrity analysis, Mixed-Signal simulation, and when using the Situs Autorouter.

The information contained within a message can be broken down into several distinct areas:

  • Class - the class of the message is dependent upon the Source. For example, messages regarding the compiler include InfoWarning, Error, and Fatal Error classes, while messages regarding the Autorouter include Routing Status and Situs Event.    
  • Document - the source document of the message.
  • Source - the server or engine that performed the task when the warning/error/violation was encountered (e.g., the Compiler).
  • Message - the message itself.
Each message is also date and time stamped and assigned a specific number within the list of messages.
  • Details - displays detailed information regarding the selected message, e.g., missing data.

Right-click Commands

The right-click menu provides the following commands:

  • Group By - select from the following choices to sort the messages:
    • Source
    • Class
    • Document 
    • None
  • Cross Probe - cross probe from the selected message in the panel to the object responsible for the message in the associated document.
  • Cross Probe Next Message - cross probe the next message in the panel.
  • Cross Probe Previous Message - cross probe the previous message in the panel.
  • Waive Violation - waive the selected violation(s). Launches the Waived Violation Info dialog, in which you can document information about waived violations, including when the violation was waived, who waived the violation, and the reason for waiving the violation.
Waived violations are displayed on the board in a separate color from other violations. Color settings can be changed using the View Configuration panel.
  • Place Specific No ERC for this violation - place a specific No ERC for this violation in the schematic. 
  • Clear All - clear all messages that are currently displayed in the panel.
  • Clear Selected - clear all selected messages from the panel.
  • Clear Class - clear all messages from the panel that are of the same class as the currently selected message.
  • Save - save the current list of messages in the panel to a file. After launching the command, the Save Message List To File dialog appears. Use this dialog to browse to a particular destination in which to save the file and to give the file a new name (if required).
  • Save Selection - save selected messages in the panel to a file. After launching the command, the Save Message List To File dialog appears. Use this dialog to browse to a particular destination in which to save the file and to give the file a new name (if required).
  • Export To Report - select to export all listed messages to a report. 
  • Copy - copy the selected messages to the Windows clipboard.
  • Print - preview and print a report containing all messages currently listed in the panel.

When cross-probing (where applicable) from a message in the panel to the offending object(s) on the affected document, you will either be taken directly to the object on the associated document, or indirectly, depending on the particular source of the message.


  1. Not all messages can be cross probed. You can only cross probe from a message if it has a valid (existing) associated document, which is specified in the Document field of the message.
  2. When cross-probing to a PCB document:
    • Ensure that the relative PCB document is the active document in the design editor window, otherwise cross probing will occur but you will not jump to it in the document.
    • The offending object(s) will be automatically zoomed and centered (where possible) in the design editor window. Highlighting options available from the PCB panel have no affect on the display.
  3. When cross-probing to a schematic document:
    • The document will be made active if it is not already.
    • The visual display of a cross-probed object on a schematic document in the design editor window is dependent upon the highlighting options defined on the System - Navigation page of the Preferences dialog. These options include zooming, selecting, and dimming; the latter causes all other objects on the document to become dimmed leaving only the offending object fully visible.
    • The filtering applied when cross probing from the Messages panel is temporary. Clicking inside the design editor window will clear the filter so that you are not prevented from selecting or editing design objects that fall outside the scope of the filter.
    • The extent of 'dimming' applied when the dimming option is enabled can be manually adjusted using the Mask and Dim Settings region on the View Options tab of the View Configuration panel.
  4. Data may be sorted by any column by clicking on the header for that column. Click once to sort in ascending order; click again to sort by descending order.
  5. You can change the order in which columns of data are displayed. To move a column, click on its header and drag it horizontally to the required position. A valid position is indicated by the appearance of two blue positional arrows.
  6. Clearing messages does not necessarily mean the messages have been resolved. The same unresolved messages will be listed after performing the same command that led to the messages being generated initially. Message clearance is a visual aid when resolving errors in the design that allows you to manually remove messages as you feel they have been resolved. The initial command must be launched again to obtain an up-to-date picture of any violations that still exist.
  7. Clearing all messages is particularly useful when you do not want any previous messages from any other sources to confuse warnings and errors that have been generated from the last command. In some cases, running a command will automatically clear the Messages panel prior to populating it with a fresh list of messages that are generated as a consequence of running that command.
  8. With respect to PCB/Compiler/Comparator-specific messages, if the associated document is closed, the corresponding message entries will be automatically cleared from the panel. For example, if you run a DRC Check on a PCB document, any violation messages listed in the Messages panel for that document will be cleared from the panel if the document is closed.
  9. When a file or document has been removed from an opened project, a warning message will be displayed in the Messages panel to clarify the reason for the project modification.
