Offense is not an option.

This Verilog code is very terse. It is a Register Transfer Logic (RTL)
style similar in spirit to the LOLA code that was published in the book
"Digital Circuit Design for Computer Science Students". The downside of
the RTL style is its focus on structure of the circuit rather than on

Fortunately, HDL can be expanded, commented, and restructured to become
more "behavioral" in style while doing exact same thing.
