DFT help
Hi,
I am confused by a dft problem now. Since the scan chains from fontend are not enough, the test coverage is a little low. Someone told me that increasing the length of every scan chain could resolve this problem. But I did not constrain the the length of every scan chain. The test coverage is still not high. What should I do to increase the length of each scan chain and the test coverage?
Best Regards,
