We previously covered the Free VHDL book. Now Viswa tipped us to this Free digital design text book : Digital McLogic Design
This text presents introductory digital logic design concepts and introductory VHDL modeling concepts. This book focuses on block-level design and has removed many of the unimportant low-level digital design details typically found in introductory digital design texts. This book results from the authors’ experience from working with students and teaching digital logic design.

Xula is the company that makes the FPGA for the Gameduino.
Hmm. Pretty sure Xula and Xula2 are FPGA development boards from xess.com based on Xilinx FPGA parts. The Gameduino (http://excamera.com/sphinx/gameduino/) also uses a similar Xilinx FPGA to the Xula (in Arduino shield form factor) to provide VGA graphics, but other than that, I don’t think there is a connection. Xess has also made a free FPGA tutorial that readers of this post might be interested in: http://www.xess.com/appnotes/FpgasNowWhatBook.pdf
Hey, my professor wrote that book
