system architecture

+'s This is an excellent book for the one that has an inkling
of what VHDL is about.
There is a lot of detail of language definition and how the
language came about.
This author is very good at explaining a point.

-'s There is very little in this reference concerning non-
synthesisable code AND why can't folks index books? I would
really like to buy a book that I didn't have to re-read to
revisit a particular detail, L

I am an EE but spent most of my career programming in C. This book is an excellent tutorial, beginning with the basics and gradually covering the more complex aspects of VHDL. It clearly explains the difference between sequential (traditional) programming and concurrent programming--both are used in VHDL. It also clearly defines the differences between the modelling stage (not covered in detail) and the design stage (Register Transfer Level - which is covered in great detail). Finally, he explains how to set up a test bench. Within 2 months of reading this book, other engineers were coming to me for advice. I literally wore out the binding!
