Abstract :
This paper presents a method for watermarking standard-cell designs in a mixed-signal design environment. The method utilizes the constraints that are placed on a mixed-signal standard-cell design in terms of routing layers, utilizing feedthroughs to watermark the standard-cell portion of the design. The design is watermarked by modifying placement of feedthroughs in the design, allowing the designer flexibility in their placement
