After a brief explanation of the principals of the JTAG interface on chip- and board level, examples will be presented of peripheral circuitry around FPGA’s which can well be functionally validated
using the JTAG interface on your (prototype) board. At a later stage this Boundary Scan method also turns out to be valuable as production test tool and in system programmer.
