  LOINS("sum_y","name","pi","ci","si","c0b","f","vdd","vss",0);

DESCRIPTION
- Interface
   entity sum_y is
     port(
        pi : in bit;
        ci : in bit;
        si : in bit;
        c0b : in bit;
        f : out bit;
        vdd : in bit;
        vss : in bit);
- Logical description
   f <= not (((si and pi) and ci) or (c0b and ((si or pi) or ci)));

- Physical features
