Complete the architecture below to build an 8-bit saturating adder: add the two operands, but if the sum is greater than what can be represented by the 8-bit output, let it saturate (take its maximum value) rather than rolling over. For example, 200 + 100 should equal 255, not 44.

Hint: you'll know you need to saturate if the 8-bit result would overflow. One or more intermediate signals might help here.
library IEEE; use IEEE.std_logic_1164.all; use IEEE.numeric_std.all; entity saturatingadd is port( a : in unsigned(7 downto 0); b : in unsigned(7 downto 0); result : out unsigned(7 downto 0) ); end saturatingadd; architecture synth of saturatingadd is begin result <= a + b; end;

Build output:
