Voltage Optimization Modules
Two patented IPs and a design methodology to estimate and track the minimum supply voltage (Vmin) for each individual circuit in the field:
* TMFLT-S IP (Timing Fault Sensor)
Estimates the Fmax/Vmin of the circuit during a calibration phase
* TMFLT-R IP (Timing Fault Ring) :
Tracks either the minimum voltage operation (Vmin) or the maximum clock frequency (Fmax) during run-time phase
* TMFLT Sensor implementation methodology:
Allows choosing the best register candidates to insert TMFLT Sensors. Allowing to minimize the area overhead to less than 2%.
