Vhdl by Douglas L. Perry (1993, Hardcover, Subsequent Edition)

I was looking for a reference on VHDL and the book does go by the basics, but due to the age, the examples may be a bit dated. The book is a fair reference. It assumes some basic electronics knowledge. I have not gone through all the book, but was looking for a good introductory book at a cheap price. Thus, I picked up this one off eBay inexpensively.
