In this paper, a novel way to finely tune a net delay on Xilinx Field Programmable Gate arrays (FPGAs) is proposed. It consists of adding floating interconnects (nodes) to the net on which the delay is to be tuned, connected to any input pin of a switch matrix along the net. Adding nodes is made with a TCL script applied to an already placed and routed design. However, such nodes, also called antennas,...
Despite the perceived lightweight and structural regularity of Arbiter PUF (APUF), high quality (bias -- free) large APUF implementation on FPGA has traditionally proved to be challenging. Currently, the most widely accepted design approach for FPGA -- based APUF implementation is the Programmable Delay Line (PDL) based APUF. In this work, we describe a scalable design methodology to implement close-to-ideal...
This paper proposes a novel approach for efficient implementation of a real-valued arbiter-based physical unclon-able function (PUF) on FPGA. We introduce a high resolution programmable delay logic (PDL) implemented by lookup table (LUT) internal structure. Using the PDL, we perform fine tuning to cancel out delay skews caused by asymmetries in routing and systematic variations. We devise a symmetric...
