I looked at their website and was not too impressed. They charge a sign-up fee of I believe $28 and then $14 per "course". However, each "course" is really one lesson and the Verilog series is about 14 lessons. While it appears cheap at the start, you will probably pay $200 just to read their HTML pages on Verilog.
A better deal may be the book:
Verilog Computer-Based Training Course
This McGraw-Hill book comes with a CD that contains a Verilog Training Course and software simulators to help you apply what you have learned. I am not affliated with this book, but I am seriously considering purchasing it. Has anyone used this training?
