Abstract
A method and apparatus for reducing pin overhead in a non-scan design for testability, The method comprises connecting control signals of test points l£l£, . . . , £lto a first primary input PIthrough AND gate switch, connecting control signals of test points l, . . . , £lto a kth primary input PIthrough AND gate switch until every test point is connected to one of the primary inputs PI, PI, . . . , PI, connecting a 1-control point to AND gate directly, connecting a 0-control point to AND gate through inverter, sharing one AND gate among all control points that are connected to the same primary input, controlling all control points by an uniform test signal, and checking whether the test points and the primary inputs produce new re-convergent fan-out while reducing inputs of the control signals.
