VHDL BY EXAMPLE

The best VHDL intro I have found. A must have book for beginners.(Trust me - you will regret not starting with this)

Recommended lecture for electronics and Embedded systems students using FPGA and VHDL.

In my opinion this would be invaluable for migrating from Verilog to VHDL, where you already have a good grasp of FPGA concepts and a goal in mind. Alternatively it could be a good textbook to support a course.Don't expect it to teach you though.

Simple and effective book for starting
