Hi serhannn,
Please when posting a DRC/LVS/QRC error you should be more specific,that is you should show the exact error given by assura/calibre etc...For your case,i think that you should create a n-well contact ring around your pmos transistors and then connect this ring to Vdd.Give it a try and see if this corrects the error.
N-Well contacts can be found from library manager as all other technology components and you should cover all of the ring with metal M1 and then connect it to Vdd.You should also leave the ring "broken" wherever you want and not "close" it as a real ring.
Regards,
