FPGAs are used in many long-life systems that serve mission-critical needs. The supply chain and life-cycle management of these devices have long relied on ensuring adequate controls are in place. In this paper, a technique is presented that provides measurement vectors by determining both characteristics of the supply properties of the FPGA and characteristics of aging of the FPGA. Asynchronous ring oscillators are placed throughout the FPGA, and the measurement of these oscillators is compared to other chips both within a manufacturing lot and between other manufacturing lots. Through these non-invasive measurements, the “health history” of the FPGA can be evaluated and utilized in supply chain decisions before and during system operation.
