High Quality Content by WIKIPEDIA articles! Scan chain is a technique used in Design For Test. The objective is to make testing easier by providing a simple way to set and observe every flip-flop in an IC. A special signal called scan enable is added to a design. When this signal is asserted, every flip-flop in the design is connected into a long shift register, one input pin provides the data to this chain, and one output pin is connected to the output of the chain. Then using the chip's clock signal, an arbitrary pattern can be entered into the chain of flips flops, and/or the state of every flip flop can be read out.
