Regenerate the layout of the current IP integrator subsystem design in the open canvas. This command updates and redraws the graphical elements of the subsystem design in the AMD Vivado™ IDE.


-hierarchy <arg> - (Optional) Specify a hierarchical module to regenerate. Use the get_bd_cells command to specify the hierarchical module as an object.

-layout_file <arg> - (Optional) Specify a native format block design layout file that was written by the write_bd_layout command.

-routing - (Optional) Refresh the routing in the IP integrator canvas, but do not refresh the placement of objects.

-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.
