Signal Integrity (SI) and Power Integrity (PI) issues are critical to analyze, ensuring the proper operation of PCB systems and IC packages, yet the computational demands from EDA tools can cause engineers to only analyze what they deem are critical signals, instead of the entire system. Cadence has managed to overcome this SI/PI… Read More
The power integrity (PI) of a system is an extremely important aspect to be looked at all levels – chip, package and PCB for overall reliability of the system. At the PCB level, a DC analysis, usually based on IR drop, must ensure that adequate DC voltage, satisfying all constraints of current density and temperature, is delivered… Read More
