I think built in self test is used to test memory and connection in circuit
memory BIST
LOGIC BIST

just for example , we made micro controller circuit . If decoder circuit in microcontroller is faulty , how does circuit detect fault by self checking that decoder is faulty ?

I think we need test vector and we have to check out that all connection are correct

but confused how we will do ?
