Abstract: A voltage detection circuit includes a tunable delay circuit that receives a supply voltage and that generates a delayed signal in response to an input signal. A control circuit causes a first adjustment in a delay provided by the tunable delay circuit to the delayed signal. An error detection circuit generates an error indication in an error signal in response to a change in a timing of the delayed signal relative to a clock signal caused by the first adjustment in the delay provided to the delayed signal. The control circuit causes a second adjustment in the delay provided by the tunable delay circuit to the delayed signal in response to the error indication. The error detection circuit causes the error signal to be indicative of the supply voltage reaching a threshold voltage after the second adjustment in the delay.

Abstract: A detection circuit includes a tunable delay circuit that generates a delayed signal and that receives a supply voltage. The detection circuit includes a control circuit that adjusts a delay provided by the tunable delay circuit to the delayed signal. The detection circuit includes a time-to-digital converter circuit that converts the delay provided by the tunable delay circuit to the delayed signal to a digital code and adjusts the digital code based on changes in the supply voltage. The control circuit causes the tunable delay circuit to maintain the delay provided to the delayed signal constant in response to the digital code reaching an alignment value. The detection circuit may continuously monitor timing margin of a data signal relative to a clock signal and update the digital code in every clock cycle. The detection circuit may be a security sensor that detects changes in the supply voltage.

Abstract: An apparatus to facilitate runtime fault detection, fault location, and circuit recovery in an accelerator device is disclosed. In one implementation, the accelerator device comprises a sensor network comprising a plurality of sensors; a secure device manager (SDM); and a sensor aggregator communicably coupled to the sensor network and the SDM. In one implementation, the sensor aggregator can receive sensor data from the sensor network; analyze the sensor data to detect a fault condition; determine a spatial location of the fault condition based on the sensor data; and generate an event for the SDM to cause the SDM to mitigate the fault condition.
