WebThe boundary scan cells then record the actual outputs and the resulting inputs on other pins, and the results are sent to the PC software for analysis. In this way, nets suffering from open-circuit, short-circuit or “stuck-at” faults are located, and key devices are confirmed to be operational and correctly placed. http://www.jtagtest.com/faq/jtag-ieee-1149-1/how-does-boundary-scan-work
