Fpga Chip Identificaton Generator Using Digital Clock Manager
S. Rexlin Leveena · 2013
Physically Unclonable Functions (PUF) are commonly used in applications such as hardware security and property protection. Various PUF implementation techniques are used to translate the chip-specific variations into a unique binary string. It is difficult to maintain the repeatability of FPGA chip ID generation, especially used over a wide range of operating conditions. To overcome this problem, configurable ring oscillator, orthogonal re-initialization scheme to improve repeatability. We propose a Digital Clock Manager (DCM). It is used to generate the digital clock signals.
