摘要

A method for creating an architecture to support Q-gating for launch-off-shift (LOS) scan testing using a plurality of flip-flops is provided. The method may include applying a common clock signal to each clock input of the plurality of flip-flops and applying a gated scan enable signal to each scan enable input of the plurality of flip-flops. The method may further include applying a global scan enable signal directly to each of a plurality of Q-gates corresponding to each of the plurality of flip-flops, wherein the global scan enable signal traverses a signal path that bypasses combinational logic located between any two flip-flops of the plurality of flip-flops.
