There is no student workbook or ebook, but you can download the HyperLynx demo which has a very detailed tutorial that will introduce you to some signal integrity basics and walk you through the product. The demo is locked to specific designs, so you don't have the liberty of doing your own design work here, but if you are at a university, you may already have a license, so you can use the licensed product for your own experimentation.
If you fill out this registration form, you'll get a download link for the demo software.
Mentor used to comile traning book for thier product. For Hyperlynx, there was a book title" Hyperlynx Signal Integrityy Analysis Student workbook" in 2002. The part number was 069717. I guess Mentor still have this type of workbook for new release. I understand It belongs Mentor's properites and can't exposed to outside.
I ageree the online tutorial is more better than the workbook if user wish to learn how to use the tool. For SI basic concept, I recommand Eric's book.
