Characteristics with use of scan designs

Question

Explain the characteristics associated with the use of scan designs?

Answer 1

Some of the attributes that are associated with the use of scan designs are following:

a) Flip-flops and latches are more complex. Hence, scan designs are expensive in terms of board or the silicon area.

b) One or more additional I/O is required.

c) Test generation costs may be appreciably decreased. This can also lead to the higher fault coverage.
