Stridge Customer Empowerment: Debug Tutorials

Voltage Droop Debug
Intended Audience
Test engineers, design engineers involved with silicon debug of @speed tests.

Tutorial Summary
Voltage droop is the invisible, undesirable and unavoidable effect of GHz speeds in
nanometer designs. Voltage droop is formed when system speed and circuit speed
paths get exclusive engineering attention at the expense of power management. Voltage
droop is like cholesterol, a silent killer. Voltage droop can cause test escapes, it is a
reliability and quality hazard, and can cause massive field returns.

This tutorial explains the tests and circuit behavior causing the voltage droop. The
attendees will learn to detect the presence of voltage droop. Last but not the least, this
tutorial shows proven Design for Debug (DFD) methods to prevent voltage droop.
