ok, what I would like to do is assign a smaller std_vector to a large one, padding out the upper bits with zeros. But, I want something generic and simple that doesn't involve knowing the size of each first. for instance if I have: signal smaller_vec: std_logic_vector (15 downto 0); signal larger_vec: std_logic_vector (31 downto 0); I could do ... WebMay 21, 2010 · That is because data(0 downto 0) returns a std_logic_vector of length 1. data(0) returns a std_logic .
