Using Message Filters
As the software processes your design, various messages are generated. In some cases, you may want to suppress a particular message from appearing. For example, you may get a warning message about an unconnected pin that you intend to be unconnected. To suppress the message from subsequent runs of the software, you can use Message Filters.
You can filter most messages that begin with "WARNING" or "INFO" and are followed by a library name and message number. For example, the following message can be filtered:
Image Xst:454: message text
where Xst is the library name and 454 is the message number. In this case, the library name is the internal Xilinx® library that stores the message.
Note Error messages cannot be filtered. Additionally, messages for some processes cannot be filtered (for example, messages generated by third-party software, such as the Synplicity software). If you try to filter a message that cannot be filtered, a dialog box appears that states that the message cannot be filtered.
Caution! When you suppress a message, it does not fix the issue. Do not filter messages for issues that must be fixed.
To Filter Messages
  1.  In the upper left pane of the Design Summary, select Summary.
  2.  In the lower left pane, select Enable Message Filtering.
    Note This enables message filtering for the project.
  3.  In the upper left pane, click a title under the Errors and Warnings heading.
  4.  In the right pane, right-click the message to filter, and select one of the following commands:
    •  Filter All Instances of This Message - to filter out all messages with the same library name and message number, regardless of the message text.
    •  Filter This Instance Only - to filter out all messages with the same library name, message number, and text.
    •  Edit Message Filters - to open the Edit Message Filters dialog box, which allows you to define custom filters.
      Note To open the Edit Message Filters dialog box, you must have only one message selected.
When you run the software, the filtered messages are suppressed from the Console panel and from reports. To view new messages generated by the most recent software run, select All Current Messages under the Errors and Warning heading in the upper left pane of the Design Summary. To edit message filters, see Editing Message Filters.
