Intellectual property metering(5)

Abstract. We have developed the first hardware and software (intellectual property) metering scheme that enables reliable low overhead proofs for the number of manufactured parts and copied programs. The key idea is to make each design slightly different d

During logic synthesis of control path we can create for some states redundant equiv-alent states. Each of variables will obtain different state assignments, and we can use any of the assignments of the two equivalent states. If these step is repeated n times, we will have 2n different solution. The remainder of the paper is organized in the following way:

We first survey the related literature. Next we formulate the metering problem by estab-lishing objectives and figures of merit. After that, we propose and analyze a number of hardware and software metering techniques. Probabilistic analysis of the metering tech-nique and explanation of technological and implementation issues is given in Section 5.After that we present our synthesis and optimization approach and algorithm. Finally, we present experimental results and conclude by briefly discussing future potential metering directions.
