In recent years, synthetic test instruments have become increasingly popular in the automatic test equipment (ATE) market. This type of instrument gives users the ability to create custom solutions to better meet their test requirements. FPGA (Field Programmable Gate Array) based solutions are the most common synthetic test instrument on the market today. FPGA based solutions can work well due to...
A ring oscillator physical unclonable function (RO PUF) is an application-constrained hardware security primitive that can be used for authentication and key generation. PUFs depend on variability during the fabrication process to produce random outputs that are nevertheless stable across multiple measurements. Unfortunately, RO PUFs are known to be unstable especially when implemented on an Field...
