A full effective coding with vhdl guide must discuss reset. Two major schools: : Favoring clock-driven logic over asynchronous circuits to
signal a : std_logic; signal b : std_logic_vector(7 downto 0); signal b : std_logic_vector(7 downto 0)
Every signal declaration represents a physical wire or a storage element.
