Hi all, I get an error as : Range expressions could not be resolved to constant in the for loop: for i in nshft-1 downto 0 loop where - signal nshft : integer range 32 downto 1; Is it because that I am assigning an integer with a range limit to a constant iterator in for loop? In that case what would be the solution? Please see the code and screenshot attached. Thanks and regards, Rohan Narkhede

"Range" in this error message is the loop range "nshft-1 downto 0". A for-loop in VHDL is only allowed with constant values for synthesis. Obviously nshift is not a constant value... Look at the barrel shifter in https://embdev.net/topic/346009 BTW: Only one thread with the same question pls.
