just beginning

GKM and Tricky,

Thanks for the replies. Both replies make sense. I like the idea of HDL being a writing language. What I keep running into with the textbook is good explanations of the circuit action but vague explanations on why the author set up the code as he did. In one case, the author describes a D latch. I did not find any explanations of what the symbols were or meant until reading a few pages later. I don't mean to gripe about the book, but this situation makes me wish that I had some kind of tutorial that would explain the terms and how to use them to describe the ciruit action. I know that learning any kind of HDL or programming language takes a lot of work and understanding only comes by doing the work. But a person has got to start somewhere.

Thanks again.

Rick
