WebMay 28, 2014 · data (i) is a single std_logic. You cannot do std_logic * std_logic_vector. Hence, there is no possible result, and to_integer is not appropriate. 4. i <= i + 1; is illegal as i is a constant, not a signal. 5. you cannot cast in integer to a std_logic_vector directly, you need to go via the signed or unsigned type. WebJul 5, 2011 · You can even use integers if you like. For some reason, many VHDL designers want to use std_logic_vectors on ports - there is no need.
