access, A variety of data type whose numeric_std is a library package defined for VHDL. It provides arithmetic functions for vectors. This package contains overloaded arithmetic operators on the SIGNED and UNSIGNED types. The package also contains useful type conversion Description: The operator is called overloaded if there is more than one function specifying it for different data and result types. VHDL allows defining operators of The logical operator xnor is not provided in VHDL-87.

It can be used to combine two or more items together. Since VHDL is strongly typed, it requires that all inputs to the concatenation be of the same type. Additionally, the result of the concatenation needs to exactly fit … VHDL. There are also several built-in operators that can be used with those This section mentions some of these. The logical operators NOT, AND, OR, NAND, NOR, and XOR can be used with any bit type VHDL Operators 1.

• Other relational operators than ’=’ and ’/=’ are dependant upon the order in the enumerated type. The simplest elements to model in VHDL are the basic logic gates – AND, OR, NOR, NAND, NOT and XOR. Each of these type of gates has a corresponding operator which implements their functionality.
