Hi,

which logic gate gives :

x y result

0 0 1

0 1 0

1 0 1

1 1 0

this is the question :

if (A = '1') and (B = '1') then tempY <= '0';

elsif (A = '0') and (B = '0') then tempY <= '0';

else tempY < = '1';

end if;

if (A = '0' and B = '0') then tempZ <= '1';

elsif(A = '0' and B = '1') then tempZ <= '0';

elsif(A = '1' and B = '1') then tempZ <= '0';

elsif(A = '1' and B = '0') then tempZ <= '1';

end if;

end process;

Y <= tempY;

Z <= tempZ;

Y is an xor gate

but what is z

This is NOT y. The x input has no effect on the output.

B
