In the Messages window (shown in the following figure), messages are categorized according to design step and severity level: Errors, Critical Warnings, Warnings, Info, and Status. To filter messages, select the appropriate check boxes in the window header. You can expand the message categories to view specific messages. You can click the Collapse All icon to show only the main design steps. This enables better navigation to specific messages. Many messages include links that take you to logic lines in the RTL files. For more information, including advanced filtering techniques, see this link in the Vivado Design Suite User Guide: Using the Vivado IDE (UG893).
