A new watermarking method for intellectual property (IP) protection is presented. The proposed method uses a uniquely generated stream of bits, known as a watermark, embedded into the self-test circuit to represent ownership. This scheme can detect the ownership rights of the IP provider even when the chip has been packaged. Experimental results show the proposed embedding technique can survive synthesis, placement and routing. The experimental results are given to demonstrate the proposed method.
