Hierarchical clock gating
Web10 de fev. de 2012 · A renewed emphasis on high-frequency clock design has heightened interest in multisource clock-tree synthesis (CTS). This tutorial covers how to implement a multisource CTS design. Web11-13-2013 11:50 PM. Well, it seems to work for you, so take the following with a grain of salt. On FPGAs, any kind of logic generated clock tends to have skew issues. The two possible approaches to clock gating are (in Altera terms): a) use the ALTCLKCTRL that sits atop the clock distribution trees b) use the clock gating logic in each LAB.

WebIn simplest form a clock gating can be achieved by using an AND gate as shown in picture below. Figure 1: AND gate-based clock gating. The clock enable signal, generated by a combinatorial logic, controls when to provide the clock to the downstream logic (FF in the above figure). When enable is 1, the clock will be provided to FF and when ... WebHi I am working on ASIC prototyping and using virtex-7 2000t FPGA.

This can be a low-power state where in low activity scenarios, the power that the clock tree consumes can be saved. list of bent moleculesIn computer architecture, clock gating is a popular power management technique used in many synchronous circuits for reducing dynamic power dissipation, by removing the clock signal when the circuit is not in use or ignores clock signal. Clock gating saves power by pruning the clock tree, at the cost of adding more logic to a circuit. Pruning the clock disables portions of the circuitry so that the flip-flops in them do not have to switch states. Switching states consumes power.
