The application of boundary-scan technology to FPGA-based experiment system

Boundary-scan technology is a popular testing method. Applying boundary-scan technology to FPGA-based remote experiment system is brought forward and realized in the paper. ldquoConfigurerdquo and ldquoverifyrdquo are the two key steps in the process of FPGA-based experiment. Using boundary-scan technology as electric probe, we can realize both of the key steps. To improve the integral preference of the whole remote experiment system, we have designed a hardware boundary-scan controller with VHDL to configure and verify the target FPGA, and it works effectively. This scheme of adopting boundary-scan technology is simple, economical and stable, and has more advantages compared with other schemes. There are no precedents applying boundary-scan testing technology to the experiment system in education field, so the idea is original.
