Vivado categorizes messages in the Messages window by design step and severity: Errors, Critical Warnings, Warnings, Info, and Status. Filter messages by selecting check boxes in the window header.
Expand the message categories to view specific messages. Click Collapse All to show only main design steps, making navigation easier. Many messages include links to logic lines in the RTL files. For more information and advanced filtering techniques, refer to the Vivado Design Suite User Guide: Using the Vivado IDE (UG893).
