Size of an array

[kwaj]

Is there a command to return the size of an array?

Hi Kwaj,
No "command", but an attribute of a vector named Length

a_vec'length

Is there a command to return the size of an array?

There is a predefined attribute that will do this:

A'Length (n) returns number of values in the n-th index range of array A
For a single-dimensional array (n) can be omitted.

A'Length can be used like this:

signal b : std_logic_vector( A'Length - 1 downto 0 );


or almost anywhere where you would want to plug in the length of A
