摘要：A low power scan flip-flop cell includes a multiplexer, a master latch, a scanslave latch and a data slave latch. The master latch is connected to the multiplexer, andused for generating a first latch signal. The scan slave latch is connected to the masterlatch, and generates a scan output (SO) signal. The data slave latch is connected to the

master latch, and generates a Q output depending on a scan enable (SE) input signal andthe first latch signal. The Q output is maintained at a predetermined level during scanmode, which eliminates unnecessary switching of combinational logic connected to thescan flip-flop cell and thus reduces power consumption.
