3. Add metal1 and contact to both nplus and pplus and connect them to VCC and GND respectively.

   

   Figure 4-20. connect well tie to VCC and GND

   Notice that the PMOS's source is connected to VCC and NMOS's source is connected to the GND. By connecting the body of the wells to the sources through metal1 we are connecting the Nwell to VCC and Pwell to the GND.
