A cost-efficient delay-fault monitor
A cost-efficient delay-fault monitor
Delay-fault monitoring sensors are widely used for Dynamic Voltage and Frequency Scaling (DVFS) to compensate for intrinsic Process, Voltage, Temperature and Ageing (PVTA) variations. Such techniques are generally based on monitoring the circuit’s critical paths. This paper presents a new delay-fault monitoring circuit, which is able to monitoring multiple paths simultaneously. The proposed circuitry has been designed and verified in a 32 bit MIPS processor using a 65nm technology. Our results indicate that the use of the proposed sensor for delay monitoring can lead to a significant saving in area and power overheads of two-thirds and one-third, respectively, compared to a canary flip-flop.

Abstract
Delay-fault monitoring sensors are widely used for Dynamic Voltage and Frequency Scaling (DVFS) to compensate for intrinsic Process, Voltage, Temperature and Ageing (PVTA) variations. Such techniques are generally based on monitoring the circuit’s critical paths. This paper presents a new delay-fault monitoring circuit, which is able to monitoring multiple paths simultaneously. The proposed circuitry has been designed and verified in a 32 bit MIPS processor using a 65nm technology. Our results indicate that the use of the proposed sensor for delay monitoring can lead to a significant saving in area and power overheads of two-thirds and one-third, respectively, compared to a canary flip-flop.
