VHDL Coding Guide

By our (long) experience, many designers code without using any Coding Guide.
From the smallest one-man operation to the largest multi-national company, this is never good.
However, we have also seen some totally counter-productive Coding Guides (usually in large companies).
This was the motivation in creating this document in 2004. Surprisingly, this Guide has remained extremely stable and the 2016 version is very close to the original version, which is an indication of its quality !
