Where could I find a primer on "digital design process"?

Dear Camilla log, 

Here is a helpful primer: 

M. Morris Mano, ?Digital Design,? Prentice Hall, 3rd Edition, 2002 See
<http://cwx.prenhall.com/bookbind/pubbooks/mano2/>

Other ones, more specified: 

Analysis and Design of Digital Systems with VHDL /Allen Dewey

Digital Design: Principles and Practices and Xilinx 4.2i Student
Package (3rd Edition) by John F. Wakerly

Simplifying Digital Signal Process by Rajesh J. Shah 

All available at Amazon.com (www.amazon.com). 

I hope this answered your question. I searched for "digital design
process" with the terms "primer", "introduction" and "textbook".
Please contact me if you need any further clarification on this answer
