Coset error detection in BIST design
Prawat Nagvajara, Mark G. Karpovsky · 2003
A finite-field algebraic description of a built-in self-test (BIST) design based on primitive feedback shift registers (LFSRs) implementing the test generator and the signature analyzer (SA) is presented. That the BIST schemes that use the TG and the SA with the same feedback polynomial detect errors which distort the output functions of the circuits-under-test for a set of the input vectors forming a coset of a subspace. The authors term this type of error the 'single coset error'. Signature schemes which detect the coset errors of multiplicity r are further described, (r>
