The SEVERITY property lets you change the severity assigned to individual design rule checks (DRC) in the Vivado Design Suite when running Report DRC. For more information on Running DRCs, see this Vivado Design Suite User Guide: System-Level Design Entry (UG895).
You can set the severity of both built-in and custom DRCs. For information on writing custom design rule checks, see this Vivado Design Suite User Guide: Using Tcl Scripting (UG894).
As an example, the following command can be used to downgrade an Error to a Warning.
set_property SEVERITY {Warning} [get_drc_checks REQP-83]To restore the DRC objects to the default setting, use the
reset_drc_check
Tcl command. Built-in DRC checks are
returned to their default settings as defined by the Vivado tool. Custom DRCs are returned to their default settings as
defined by the
create_drc_check
command that created it.
