“…For that purpose a grid of temperature sensors [5] has been placed among the heaters. Since the steady-state temperature and the dynamic temperature response to a synthetic heat source depend on the ambient conditions, unlike the authors of [4], we value more the power consumption results. Apart from maximal heater power output and temperature increase we measured power as a function of heater size and PWM settings.…”

“…To date the best performing heaters in terms of raw power density could be obtained in FPGAs by configuring their Look-Up Tables (LUTs) to operate as a set of 1-stage Ring Oscillators [4,5]. However, RO architecture is sensitive to voltage level changes, which is not the case for synchronous heaters.…”

“…One of the most important challenges to measuring the on-chip temperature is the restriction on the temperature ranges. Agne et al [20] introduce seven ways to make the high-tech FPGAs heat using available internal resources. In this paper, we use the heat generator circuit that has been designed in [20], i.e., the one-level LUT-based heater.…”

During the last decades, technology scaling in reconfigurable logic devices enabled implementing complicated designs which results in higher power density and on-chip temperature. Since higher operating temperature of chips is a critical problem in electronics devices, thermal management techniques are highly required. To provide a thermal map of reconfigurable logic devices, a network of sensors is needed. In this work, a ring-oscillator-based temperature sensor is used to create a sensor network. Then, a design space exploration is done among several sensor networks with the various sensor configurations including different ring oscillator length, the number of sensors in the examined network and various sampling time. We propose three criteria for exploring and comparing the efficiency of sensors network based on the thermal overhead and also measurement accuracy and precision among plenty of configurations on the Virtex-6 FPGA.
