VLSI chip is tested by test equipment and some test circuit
actually I am confused I don't understand that fault model and test circuit are different or same things
ac after fabrication chip are tested by automatic test equipment to reduce time of testing
suppose we made micro controllerwill we interface mirocontroller chip and test circuit on same chip like below circuit
_____________________
vlsi circuit + test circuit
______________________
________________________________
microcontroller circuit + fault model
_________________________________
or
will we use extra test circuit to test microcontroller chip
____________ __________
vlsi circuit + test circuit
___________ ____________________________
micro controller + delay fault model , stuck at fault
