Abstract
A system-on-chip includes a process-voltage-temperature (PVT) sensor with a filter circuit that initiates a patterned digital signal and propagates the patterned digital signal in a manner responsive to variations in semiconductor material, operating supply voltage and operating temperature of the system-on-chip. A digital comparison circuit compares the initiated patterned digital signal and the propagated patterned digital signal. A warning signal is generated in response to the comparison where there is a detection of discrepancy between the initiated patterned digital signal and the propagated patterned digital signal.
