Nigan Posted April 1, 2019 Report Share Posted April 1, 2019 Hello everyone,, I recieved my LogicStart today so as I have a few hours spare I thought I'd get cracking wth Hamster's PDF of tutorials and info. I've just finished making a 4 bit adder using the swithces and LEDs of the board and would like to know if my code looks right. It seems to work.. From right to left, the switches in 2 groups of 4 seem to add up all the way to 15. The code is here: xvideos.onl/ xnxx.onl/ chaturbate.onl/ entity switches_leds is Port ( switches : in STD_LOGIC_VECTOR(7 downto 0);LEDs : out STD_LOGIC_VECTOR(7 downto 0));end switches_leds;architecture Behavioral of switches_leds issignal x : STD_LOGIC_VECTOR (3 downto 0);signal y : STD_LOGIC_VECTOR (3 downto 0);signal carry : STD_LOGIC_VECTOR (3 downto 0);signal result : STD_LOGIC_VECTOR (4 downto 0);beginLEDs <= "000" & result;x <= switches (3 downto 0);y <= switches ( 7 downto 4 );result(0) <= x(0) XOR y(0);carry(0) <= x(0) AND y(0);result(1) <= x(1) XOR y(1) XOR carry(0);carry(1) <= (x(1) AND y(1)) OR (carry(0) AND x(1)) OR (carry(0) AND y(1));result(2) <= x(2) XOR y(2) XOR carry(1);carry(2) <= (x(2) AND y(2)) OR (carry( Quote Link to comment Share on other sites More sharing options...
