Abstract :
In this paper we evaluate and compare the robustness (i.e., repeatablilty and uniqueness) of two SRAM PUF designs, General putpose (GP) and Low-Power (LP), by means of both circuit simulatios and industrial measurements. Circuit simulations are performed on both designs while considering two technology nodes (45nm and 32nm), three temperatures and three voltage ramp-up times. Industrial measurements are preformed to validate the simulation results. The silulation results as well as industrial measurements demonstrate that GP devices provide better repeatablilty for all investigated cases (up to 4.5X better) while the uniquenesss is design independent.
