Abstract
This article presents the simulation, validation and implementation of a temperature sensor based on RO (Ring Oscillator) in order to carry out a thermal study for the detection and localization of thermal peaks in an integrated circuit (CI). The input temperature, angles, distance as well as certain frequencies will be obtained using the GDS (gradient Direction Sensor) method based on RO. In this work, a simulation with the ModelSIM tool as well as the technological validation of the degree of integration with the NCLAUNCH Cadence tool and check this type of fully digital temperature sensor includes a number of exact inverters that can be logically inserted. In addition, a DE1 FPGA cyclone of the V 5CSEMA5F31C6 family is used for implementation. Before the transition to FPGA board implementation and verification, the use of the VHDL code and its bench test is required to describe three inverters that form a ring oscillator, in order to validate the results obtained after the synthesis Quartus Prime.This document provides a solution to thermal constraints and local overheating in the design of complex systems, which has been a major concern for designing integrated circuits.
