Grouped Scan Slice Repetition Method for Reducing Test Data Volume and Test Application Time
This paper presents a grouped scan slice encoding technique using scan slice repetition to simultaneously reduce test data volume and test application time. Using this method, many scan slices that Would be incompatible with the conventional selective scan slice method can be encoded as compatible scan slices. Experiments were performed with IS-CAS'89 and ITC'99 benchmark circuits. and results show the effectiveness of the proposed method.
