Use of if-else

ARCHITECTURE ifelse of majority is

begin

    process (A, B, C)

      begin

              if (((A = '1') and (B = '1')) or

                  ((A = '1') and (C = '1')) or

                  ((B = '1') and (C = '1')) ) then

                 Y <= '1';

              else

                  Y <= '0';

              end if;

       end process;

end ifelse;

Comments:

Process is anonymous (no name)

Used an 'else' clause to specify what the output should be if the if condition test was not true.

CAREFUL! The boolean operators (OR, AND) do not have any precedence so must use parenthesis to define precedence order
