Measurement Data for "Large Scale RO PUF Analysis over Slice Type, Evaluation Time and Temperature on 28nm Xilinx FPGAs"

This repository contains the ring oscillator frequencies gathered from 217 Xilinx Artix7 devices (Part#: XC7A35T-1CPG236C) that were analyzed in and published with the paper "Large Scale RO PUF Analysis over Slice Type, Evaluation Time and Temperature on 28nm Xilinx FPGAs" at HOST 2018.

The repository is organized as follows:

Directory structure

The actual measurement data is located in the directories

• ro_frequency_temperature/
• ro_frequency_evaluation_time/

They each contain 4 files named:

• LEFT-LOWER.hdf5
• LEFT-UPPER.hdf5
• RIGHT-LOWER.hdf5
• RIGHT-UPPER.hdf5

Each file corresponds to one measurement run with one of the 4 different bitstreams/fpga-configurations described in the paper.

ro_frequency_temperature/

measured on 50 FPGAs at ambient temperatures 5 °C, 15 °C, 25 °C, 35 °C, 45 °C, 55 °C

ro_frequency_evaluation_time/

measured on 217 FPGAs at ambient room temperature

placement_information/

detailed info on placement for each bitstream in csv format

HDF5 structure (ro_ids size depends on design)

axis/

Contains axis datasets:

• board_serialnumbers
• evaluation_times
• repetitions
• ro_ids
• temperatures

These are linked to the dimensions of the actual dataset data/ro_counts and map the indexes of a dimension to a value. For example axis/temperature is linked to the dimension with the index 2 of data/ro_counts, which means that all values data/ro_counts[:,:,i,:,:] correspond to the temperature axis/temperature[i].

evaluation_times is the number of system clock cycles that were counted at 100MHz before the RO counter was stopped.

data/

contains the actual ro frequency dataset: data/ro_counts.
It contains the raw counter values for the corresponding evaluation time.

placement/

gives the slice type, x and y slice coordinates for each RO ID.

• slice_types
• x_coordinates
• y_coordinates
