Testing using the JTAG Interface

Checking interconnections without test pins

Testing using the JTAG Interface
Testing printed circuit boards by hand is difficult, if not impossible, when using complex ICs and multilayer printed circuit boards. Fortunately most of these ICs now contain special logic which allows extensive testing of the chip’s internal connections and the interconnections on the circuit board. This is achieved by using the internationally standardised JTAG-interface.
