Unformatted text preview: A and B are used to latch scan data from the scan input I and to output this data onto + L 1 and then latch the scan data from latch L 1 and to output this data onto + L 2 , which is then used to drive the scan input of the next scan cell. Sample operation waveforms are shown in Figure 2.12b. The major advantage of using an LSSD scan cell is that it allows us to insert scan into a latch-based design. In addition, designs using LSSD are guaranteed to...
