随着每一代技术的产生，由于电流和功率需求的增加，提供具有减小额定电源电压变化的时变电流变得更加困难。电力输送网络设计变得复杂得多，需要在所有抽象级别进行准确的分析和优化，以满足规范。我们描述了可用于电力输送网络设计的电源电压变化的估计技术。我们还描述了去耦电容体系，它为不断增长的高频电流需求提供低阻抗，并限制电源电压的变化。还提出了可用于性能与功率权衡的高级功率估计技术，以降低电路的电流和功率需求。
With each technology generation, delivering a time-varying current with reduced nominal supply voltage variation is becoming more difficult due to increasing current and power requirements. The power delivery network design becomes much more complex and requires accurate analysis and optimizations at all levels of abstraction in order to meet the specifications. We describe techniques for estimation of the supply voltage variations that can be used in the design of the power delivery network. We also describe the decoupling capacitor hierarchy that provides a low impedance to the increasing high-frequency current demand and limits the supply voltage variations. Techniques for high-level power estimation that can be used for performance vs. power trade-offs to reduce the current and power requirements of the circuit are also presented.
