package used throughout the book. Appendix B is a set of useful tables
that condense some of the information in the rest of the book into quick
reference tables. Finally, Appendix C describes how to read the Bachus-
Naur format(BNF) descriptions found in the VHDL Language Reference
Manual. I can only hope that you the reader will have as much fun read-
ing this book and working with VHDL as I did in writing it.
