Testing the Pattern Generation of Minimal Test Vectors for the Video Display

Testing is an experiment in which a system is exercised and the resultant behavior is examined to make sure that the system behaves correctly. System Test tests consist of elements, test vectors, and test variables. Each of these entities to create a variety of test scenarios ranging from a simple test, which runs a series of elements once to a full parameter sweep that iterates over the values of test vectors. Test vectors and test variables map data between System Test and the model or unit under test. A Composite Video Pattern Generator is constructed, which can be used as a teaching tool in the video field as well as a laboratory instrument, useful for repairing and adjusting pattern generation of video display. This work is implemented for pattern Generator video display which is having Counters and the video pixels generated in horizontal and vertical directions. The simulation is carried out to find out the minimum set of good test vectors for the four patterns.
