Frequency, Voltage and Temperature Sensor Design for Fire Detection in VLSI Circuit on FPGA

Abstract

Abstract. Fire has both destructive and beneficent qualities. According to Rig Veda, The sacrifices made to Agni (lord of fire) go to the deities because Agni is a messenger from and to the other gods, it is his beneficent quality. Our concern in this work is to control destructive qualities of Fire by airflow, ambient temperature, and the mantra of frequency and voltage. Our target FPGA is 28 nm Kintex-7 FPGA. Xilinx XPower 14.4 is in use to calculate junction temperature with variation in ambient temperature, airflow, voltage and frequency. Kintex-7 is operable until or unless temperature of device is less than 125°C. Beyond 125°C temperature, it is destined to burn. To verify Sensor functionality, simple Image Inverter is target design. FPGA caught fire when either frequency reaches 125 GHz or voltage reaches 1.7 V or ambient temperature reaches 45°C with 250 LFM airflow. When airflow is 500 LFM, frequency threshold is 160 GHz, voltage threshold is 2.1 V and ambient temperature threshold is 60°C. Therefore, frequency, ambient temperature and voltage sensor is placed to prohibit voltage, ambient temperature and frequency beyond the permissible range to save FPGA from fire.

Frequency Scaling Based Green Mobile Battery Charge Controller Sensor Design on FPGA

“…Also this devise would handy when taken for outdoor trips [6]. Work here is to design and to make universal contact less charger for hand-held device by means of electromagnetic coupling induction [7] and sensor [9]. This paper also extend the idea from voltage scaling [8] for mobile charger to frequency scaling.…”
