The FHDL Test Driver Language is designed to simplify the process of creating and running functional tests. It is capable of running tests, suppressing all but the "interesting" results, checking for errors, generating the same vector repeatedly until a condition becomes true, and generating error messages. Driver-language statements interact dynamically with the simulation to produce results that cannot be achieved in a static vector environment.
