Circuit partitioning based fingerprinting method for IP protection

The continuously widening design productivity gap in the past few decades gives high incentives to counterfeiting ICs. Existing intellectual property (IP) protection schemes demand high overheads, and some techniques like watermarking do not facilitate tracing of illegal users. In this letter, we propose a novel fingerprinting method based on post-processing on circuit partitions. We evaluate our method on the ISPD98 benchmark suite. The experimental results demonstrate the effectiveness of the proposal. The fingerprinting design is distinct because the Hamming distance between fingerprinted IP designs is large enough to resist a collusion attack.
