If you give a specific name to your error message, you can turn it off later on. This may be useful in a case where you want to see simulation behavior with only this checker turned off or if you want to run a test that ignores a certain error.
We need to override the error in a phase that runs after build_phase so all components can finish building.
In this example all errors in slave monitor are moved to warnings, as well as a specific error from the scoreboard.
