This paper presents a cost effective scheme for self-testing video graphics controller chips and boards. With the proper placement of a reconfigurable linear feedback shift register structure, the on-board video memory, the video data-path, and the RAM-DAC blocks can be self-tested. This self-test mode can be integrated as a RUNBIST option in the IEEE boundary scan standards.>
