Hello everybody I have an issue with this one line of code here: output(to_integer(unsigned(msbd) + unsigned(lsb)) downto 0) <= bit_field(to_integer(unsigned(msbd) + unsigned(lsb)) downto to...

I have a similar issue right now with this: 


left_shift_amount <= 32 - unsigned(msbd) - unsigned(lsb);
right_shift_amount <= left_shift_amount + unsigned(lsb);
output <= std_logic_vector(Shift_right(Shift_left(unsigned(bit_field), left_shift_amount), right_shift_amount));

It says that left_shift_amount and right_shift_amount do not agree as being natural types.
