Abstract:
The disclosed embodiments relate to methods, systems and apparatus for dynamic temperature aware functional safety. The disclosed embodiments provide adaptive techniques to track extended dynamic temperature range of a System-on-Chip (SOC) and automatically tune critical IP components of the SOC so that system can operate reliably even at high temperatures. The disclosed embodiments relax the overdesign of the SOC components by reusing existing components such as a ring oscillator to determine temperature at different regions of the SOC. In one embodiment, the disclosed principles use a Calibrated Ring Oscillator (CRO) temperature sensors. The CRO-based temperature sensors provide fast temperature measurement suitable for detecting dynamic temperature ranges and temperature rate of change. The CROs are existing on the SOC and do not require addition of additional sensors.
