[-verbose] Suspend message limits during command execution




This command configures features of the report_design_analysis command.

The design analysis report analyzes timing paths at various stages in the Vivado tool flow, including synthesis, optimization, placement, routing. The -max_common_paths option specifies how many setup timing paths to capture at each stage in the flow.

Note: This command returns nothing if successful, or returns an error if it fails.


-max_common_paths <arg> - (Optional) The number of paths to consider when examining the distribution of common paths across phases of implementation. Specified as an integer value less than 20,000, the default is 1000.

-quiet - (Optional) Execute the command quietly, returning no messages from the command. The command also returns TCL_OK regardless of any errors encountered during execution.
Note: Any errors encountered on the command-line, while launching the command, will be returned. Only errors occurring inside the command will be trapped.
-verbose - (Optional) Temporarily override any message limits and return all messages from this command.
Note: Message limits can be defined with the set_msg_config command.


The following example ignores the package delays during timing analysis:
