May I know why the only way to guarantee no scan hold time violations is to use LSSD ? How is the proposed circuit in Figure 3 being low power, and hold friendly ? How is adding an inverter to pin D avoids performance degradation introduced by the MUX ? How to derive the general formula of the scan test length ? Once converted to scan sequences with a 6 vector Shift test, 44 vectors result ?
