Abstract

A method and a device for testing control units are presented, serving the purpose of operation and quality testing of automotive control units. The method comprises event control of individual test steps with defined signals from and to the test unit, thus reducing the test time. The method, furthermore, encompasses a test with square wave signals applied to the control unit, which are recognized by the control unit and read out to the test unit, thus increasing the depth of the test.
