【Abstract】 An efficient built in self test (BIST) scheme is presented for carry look ahead (CLA) adders, which takes the advantages of both determinate test and pseudorandom test, and eliminates their disadvantages A set of test patterns is also introduced, which makes full use of the internal structure regularity of CLA adders, so that the set is relatively small in size and thus convenient for generation and integration Finally, a new method is presented for computing eigenvalue更多还原
