How to Become an Expert in Power Integrity Testing Webinar Series

Power Distribution Networks (PDNs) require careful design to ensure excellent power integrity, especially in high-speed designs. This 8-part series walks you through the fundamentals to advanced topics with a large number of live demonstrations.

Practical On-die Power Integrity Measurements

In this session (Part 8), Dr. Eric Bogatin will describe the direct measurement of power rail noise on the chip itself (i.e. on die). One goal of PDN design is to engineer the power delivery network to deliver low noise DC voltages to the power rails on the die. The final test of the power noise is measuring the on-die power rail noise directly. Using a simple technique, we can directly measure the on-die power rail noise for the VCC rails, and if we plan ahead of time, sometimes the Vdd rails. Eric will introduce the method and look at two examples of measuring the on-die power noise and how some of the important design features affect this noise.

Topics to be covered in this webinar:

  • What is the origin of power rail collapse
  • Measuring rail collapse on die and on the board
  • Measuring rail compression
  • Impact from decoupling capacitor location on rail collapse and compression
  • Noise on die when the board is the aggressor

Who should attend? Hardware design and validation engineers and signal/power integrity engineers interested involved in designing any aspect of the PDN.

What attendees will learn? The root cause of one type of PDN noise will be revealed and some design techniques to avoid this. Most importantly, you will learn how to measure the noise on the die and how different it is from the board level noise.

Presenter: Dr. Eric Bogatin, Teledyne LeCroy Fellow
