The OVM provides a way of ignoring errors by changing the action associated with the report settings. You have to set the action to OVM_NO_ACTION using set_id_action (this assumes the message you want to ignore has a unique ID). How you do this depends on whether the message is coming from a ovm_component or somewhere else because each component has its own settings and everything else is under a global setting from ovm_top.
