Abstract
An active security tag is embedded within the digital logic of an electronic design for logic destined for an integrated circuit such as an FPGA. The security tag includes security tag data which permits identification of the electronic design, and facilitates efforts to enforce copyrights in the designs. The security tag also includes a transmitter designed to covertly transmit security tag data to a receiver. Other information, such as error information and status information about the integrated circuit may also be transmitted. The transmitted information is concealed from detection by being hidden within background noise signals or other signals created by normal usage of the integrated circuit.
