2010-01-03 · Logical operators return a single bit 1 or 0. They are the same as bit-wise operators only for single bit operands. They can work on expressions, integers or groups of bits, and treat all values that are nonzero as “1”. Logical operators are typically used in conditional (if else) statements since they work with expressions.

"or" is three things: A unary operator (Page 120 of the file you included). Syntax: or my_vector A binary operator. Syntax my_vector1 or my_vector2; A vectorized overloaded logical operator declared in std_logic_1164 (line 145) and defined in std_logic_1164-body (lines 512 …

Section 9.5.1: Conditional Signal Assignments Worse, the logical shift infix operators actually perform arithmetic shifts.sll and srl map onto shift_left() and shift_right(), and no overloads for the sla and sra operators are provided. But the functions switch between arithmetic and logical shifting according to the types of the first operand. This means that so do the sll and srl operators, even though lexically the "l" in the names of "or" is three things: A unary operator (Page 120 of the file you included). Syntax: or my_vector A binary operator. Syntax my_vector1 or my_vector2; A vectorized overloaded logical operator declared in std_logic_1164 (line 145) and defined in std_logic_1164-body (lines 512 … Shift operator: shift left arithmetic. Shift operators are defined for any one-dimensional array type whose element type is either bit or Boolean. The arguments of sla are the array that will be shifted and the amount by a which it will be shifted.

VHDL 1076-1993 added three attributes that can be used to determine the precise configuration of entities in a design description. These attributes return information about named entities , which are various items that become associated with identifiers, character literals or operator symbols as the result of a declaration.
