DRC, Object


Delete a single user-defined design rule check from the current project. User-defined design rule checks are created using the create_drc_checks command.

Note: You cannot delete factory defined rule checks.

Once it has been deleted there is no way to recover a rule check. The undo command will not work.

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


-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.

<name> - (Required) Specify the name of a user-defined design rule check to be deleted from the current project.
