For those who have not encountered the term yet, RTL=3DRegister Transfer
Level, NOT resistor-transistor logic!!! When I first got started in FPGAs,
this term used to confuse me greatly.

It refers to a description of a digital system which is done in terms of
registers (collections of flip-flops), clock signals which control the
flip-flops, and combinational logic which is fed by the register outputs
and in turn feeds register inputs. Such a system is also called a state
machine but that term is often reserved for situations where one
intentionally, explicitly implements a set of states and actions for each
state.
