I recently has a chance to read through the book "Signal Integrity for PCB Designer" by Vikas Shukla.
The book has been written in a simple and effective manner that PCB designers in particular and High Speed Digital Designers in general will find useful.
Unlike similar books for over $100 this book is priced cheap at $55. The used ones are available at 25 bucks. The bad - the fonts are bigger. Some topics, for example how to find impedance from Allegro could be left.Few topics could have been expanded.
That being said, this book is worth every penny paid. It covers EMI, Layering, Power supply design, a bries hspice, not covered in books of Howard Johnson and Eric Bogatins.
