Abstract

There are a lot of factors causing the monitor not to work well. Examination by the technician generally involves two steps: preliminary testing for facts finding and minor problems solving, and/or followed by further hardware-repairing. This paper describes the using of XS-Board and the Xilinx-FPGA within it to create preliminary testing tool for VGA troubleshooting. The goal of this research is to evaluate how effective the using of XS-Board with FPGA XC4005XL to implement a preliminary testing tool for VGA troubleshooting. The system will generate pictures in certain patterns and colors periodically to help technician in observing the monitor. The experiment shows that XS-Board with FPGA XC4005XL inside it is capable in handling the signaling for VGA monitor to display 64 colors almost fullscreen. With only consume 15% of logic cell resources; this system is efficient enough and ready to be improved further. One of its critical characteristics is that the internal clock generator of XC4005XL has 10% tolerant in frequency variation resulting in imperfect display of fullscreen mode.
