WebIntroduction. Clock tree synthesis (CTS) is a critical step in the physical implementation flow. An optimized clock tree (CT) can help avoid serious issues (excessive power consumption, routing congestion, elongated timing closure phase) further down the flow [1]. The need for further optimizing the clock tree has emerged in one of the customer ... WebOn-chip Clock Controllers (OCC) are also known as Scan Clock Controllers (SCC). OCC is the logic inserted on the SOC for controlling clocks during silicon testing on ATE (Automatic test Equipment). Since at-speed testing requires two clock pulses in capture mode with a frequency equal to the functional clock frequency, without OCC we need to ...

WebNov 25, 2015 · Clock gating is a standard technique to reduce clock power. It is often applied in multiple levels, particularly in big industrial designs [1–4].This is illustrated in Fig. 4.Register-level clock gating is mostly realized through automatic CAD tools, e.g. by replacing load-enable registers with clock gating cells (CGCs) and normal registers, and … WebPower = Capacitance * (Voltage) 2 * (Frequency) Hence, reducing clock power is very important. Clock gating is a key power reduction technique used by many designers and is typically implemented by gate-level power synthesis tools.
