WebDec 11, 2024 · To overcome the hold violations in SA-capture mode, the approach is to perform launch and capture from two phase-shifted clocks with a specific delay. We can insert two OCC’s (On-chip clock controller) in design for two phases of the same clock-domain. This means, for a single clock-domain there are two OCC’s inserted as shown … WebThis video describes the reason behind using lockup latches for connecting scan chains together and how it resolves hold violation.
