Array Types An array is an object that is a collection of elements of the same type. VHDL supports N-dimensional arrays, but VHDL Compiler supports only one-dimensional arrays. Array ele-ments can be of any type. An array has an index whose value selects each element. The index range determines how many elements are in the array and their ordering (low to

VHDL supports N-dimensional arrays, but Foundation Express supports only one- 25 Feb 2010 A 2-D array can be declared in two ways in VHDL. Let me show some examples: 1)Using the keyword "array". type array_type1 is array (0 to 3) CAUSE: In a VHDL design file (.vhd) at the specified location, you indexed an object with an array type. However, you specified too many index arguments or too In a VHDL Design File (.vhd) at the specified location, you used the specified type as if it were an array type. However, the type is not an array type.
