DFT MEANS design for testability. 'Design for TEST or Testability' - a methodology that ENSURES a design works properly after manufacturing, which later facilitates the failure ANALYSIS and false product/piece detection

Other than the functional logic,you need to add some DFT logic in your design.This will help you in TESTING the chip for manufacturing defects after it come from fab. Scan,MBIST,LBIST,IDDQ testing etc are all part of this. (this is a hot field and with lots of opportunities)
