Abstract

An easy method to extract the current signature of a core power supply is suggested and to measure the impedance of the PDS and the voltage at the interface of interest. With modern electromagnetic simulation tools such as SPEED2000 the impedance measurement of the PDS can be eliminated, replaced by a simple time domain simulation. It is used to obtain the transient current during HRESET of a microprocessor system.

时域电压测量的瞬态电流提取

提出了一种简单的提取核心电源电流特征的方法，并测量了PDS的阻抗和感兴趣接口处的电压。使用现代电磁仿真工具，如SPEED2000，可以消除PDS的阻抗测量，取而代之的是简单的时域仿真。它用于获取微处理器系统HRESET时的瞬态电流。
