Name Description
[-scoped] Flag waiver to interpret object wildcards as scoped to the current_instance that is set

[<objects>] List of waiver objects, or a list of message objects (cells, nets, sites, etc.) for which DRC/METHODOLOGY waiver(s) were set


Waiver, Object


After report_drc, report_methodology, or report_cdc commands are run, they return messages of specific violations or conditions found in the design. These violations can prevent the design from progressing until they have been resolved or addressed in some way. The create_waiver command lets you select individual violations or specific checks that can be waived for a design, letting you move forward in the design flow.

Use the delete_waivers command to remove waivers from the design.


-scoped - (Optional) Specify that waivers should be interpreted with object wildcards as scoped to the current_instance that is set.

-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.

<objects> - (Optional) List of waiver objects as returned by get_waivers.


This example deletes all the DRC waivers in the design:

delete_waivers [get_waivers -type DRC]
