Standard Logic Operators

The following operators are defined for types std_ulogic, std_logic, std_ulogic_vector and std_logic_vector:

Logical Operators

function "and" ( l : std_ulogic; r : std_ulogic ) return UX01;

function "nand" ( l : std_ulogic; r : std_ulogic ) return UX01;

function "or" ( l : std_ulogic; r : std_ulogic ) return UX01;

function "nor" ( l : std_ulogic; r : std_ulogic ) return UX01;

function "xor" ( l : std_ulogic; r : std_ulogic ) return UX01;

function "xnor" ( l : std_ulogic; r : std_ulogic ) return ux01;

function "not" ( l : std_ulogic ) return UX01;

Array Logical Operators

function "and" ( l, r : std_logic_vector ) return std_logic_vector;

function "and" ( l, r : std_ulogic_vector ) return std_ulogic_vector;

function "nand" ( l, r : std_logic_vector ) return std_logic_vector;

function "nand" ( l, r : std_ulogic_vector ) return std_ulogic_vector;

function "or" ( l, r : std_logic_vector ) return std_logic_vector;

function "or" ( l, r : std_ulogic_vector ) return std_ulogic_vector;

function "nor" ( l, r : std_logic_vector ) return std_logic_vector;

function "nor" ( l, r : std_ulogic_vector ) return std_ulogic_vector;

function "xor" ( l, r : std_logic_vector ) return std_logic_vector;

function "xor" ( l, r : std_ulogic_vector ) return std_ulogic_vector;

function "xnor" ( l, r : std_logic_vector ) return std_logic_vector;

function "xnor" ( l, r : std_ulogic_vector ) return std_ulogic_vector;

function "not" ( l : std_logic_vector ) return std_logic_vector;
