Challenges of DFT and their Explanation

[amitk3553]

Hell all,

Please tell me about the Challenges in DFT(Design for testability).


Thanks!!!!!

Challenges are :
-> To make design fully testable with high number of fault coverage for transition.path delay and stuck-at testing...

Please more elaborate the challenges with path delay and stuck at testing????

We just need to increase the fault coverage in any how, with considering the DFT area and power overhead. whether it is through stuck at testing or transition or path delay..whatever it is..
