Power distribution networks are critical to the correct functionality of high performance digital systems. The design of such networks gets harder with the increasing speed of the digital designs they support, in particular, microprocessors. A microprocessor IC consumes an incredible amount of power despite its small physical size and a great amount of work goes into supplying high quality power to that tiny chip. Computers are implemented on boards that combine such power hungry ICs and must feed them simultaneously. This book focuses on the board level power distribution network (as opposed to package and IC).
A successful engineering implementation combines design, analysis, simulation and measurement and this book does a great job in presenting those different aspects of implementation thoroughly and coherently. The reader sees how the different disciplines complement each other in a successful project. The emphasis, however, is on simulation and measurement. I consider that a strength since the other aspects have been treated well in previous publications but this is certainly the most thorough treatment of power distribution network measurement. There is a lot of attention to detail, and one only has to go to the lab to make some measurements to see how some of those details will save you days if not weeks of frustration.
Simulation is used judiciously and for insight as opposed to "blind" verification. The judicious use of simulation may be strongly motivated by the inherent capacity limitations of today's fullwave field solvers, but it also ends up providing valuable intuition to the reader on why as well as the how. The authors have taken great pains to validate their simulation results at every step.
In a field [digital design] dominated by time domain thinking, this book provides a refreshing frequency domain approach. Although it is a difficult leap for most digital designers, it is one worth taking since the additional insights [into the signal integrity implications of frequency domain analysis] could well make the difference between a functional design and one that spends months on the testbench for debugging.
This is a book written not by pure theorists but practitioners of the field and it shows. The authors do not waste much time on hypothetical examples and plunge directly into problems they surely have dealt with themselves as they worked on high performance designs. Although the sections on modeling are rigorous, they are succinct and probably not for people not well trained in the field. But for the expert, this is an invaluable book.
