Abstract
One may use a new technique to determine the placement of exclusive-ors in each scan string of a chip may achieve improved test vector compression, and one may combine this technique with methods to minimize the overhead of the exclusive-or logic, to eliminate clock enable logic for multiple scan strings, to minimize the changes to existing test logic insertion and scan strings reordering, and to minimize the test vector compression computation time.
