Forensic engineering for resolving ownership problem of reusable IP core generated during high level synthesis

Abstract

Reusable Intellectual Property (IP) cores have become an obligatory mandate for combating conflicting objectives of maximizing design productivity and minimizing design cycle time. However, a reusable IP core needs protection against false (illegal) claim of ownership. In this paper, we propose a novel computational forensic engineering (CFE) based approach for resolving ownership problem of a reusable IP core generated during high level synthesis (HLS).Some of the major contributions of the proposed approach are as follows: (a) a novel methodology based on multiple design feature set (technology & control parameter independent) that is capable of resolving false claim of vendor ownership problem for an IP core generated during HLS (b) novel algorithms for extracting design features (from register transfer level (RTL) hardware description language (HDL)) of an IP core for determining the rightful owner (c) a novel signature free approach (with avg. runtime ∼2 s) that offers 0% hardware overhead and 0% degradation of IP functionality/quality compared to watermarking based IP ownership resolution techniques.
