Abstract: Digital Watermarking techniques are applied on sequential circuits to track the misuse of Intellectual Property (IP) core of a design. Watermarking technique for sequential circuits was first proposed by Oliviera. The issue of duplicate states in the technique proposed by Oliviera was addressed by counter-based approach given by Siddhant. Counter based approach also had its demerits and it was not very practical. In this paper, an improved counter based watermarking technique have been proposed which eliminates the drawbacks of previous watermarking techniques. The synthesis and simulation of proposed techniques has been done using Xilinx ISE and ModelSim simulator respectively.
