“This article will review the “std_logic_vector” data type which is one of the most common data types in VHDL.
In a previous article on the VHDL hardware description language, we discussed the basic structure of VHDL code through several introductory examples. This article will review one of the most common data types in VHDL, i.e., the “std_logic_vector” data type.
We will first discuss the fact that vectors allow us to have a more compact and readable VHDL description, especially when dealing with large circuits. Then, after reviewing some important features of the “std_logic_vector” data type, we will go over some coding styles that can help us avoid mistakes when utilizing vectors.”
