“…Despite the fact of increased cost and area, adding component redundancy to systems is an established way of providing fault-tolerant systems especially in safety/mission critical systems and therefore an approach to enhance system dependability. Furthermore it has been shown, for instance, in [13,14] that different parameters of analog and mixed-signal circuits can be digitally programmed or tuned. Fig.…”

“…The dependability of each active path can be tuned back to its normal value by tuning blocks that are present in this active path via available digital programming/tuning capabilities. Since normally these blocks have their nominal tuning range [13,14], each active path can be tuned back up to a specific level to try to regain system dependability. The purpose of the switch matrix is to provide greater flexibility and tuning space for the "Diagnose & Action" block.…”

The long-term functionality of any electronic system poses some requirements on the dependability of that system. Especially for critical systems it is becoming a crucial property with increasing system complexity and shrinking technology dimensions. Analog and mixed-signal systems are an important part of these critical systems. Until now little effort has been put into dependability of analog and mixed-signal systems, especially front/back-ends. This paper presents a new systemlevel platform for enhancing and analyzing the dependability of analog and mixed-signal front-ends in SoCs. Markov analysis has been used to theoretically investigate the dependability enhancement of these analog and mixed-signal front-ends based on this platform. Simulations in VHDL-AMS have also been conducted for an example target system consisting of a temperature sensor, operational amplifier and ADC to illustrate this platform. The gain parameter of the whole system, taken as an example of potential dependability hazard, has been investigated and enhanced based on this platform. The results show that this proposed platform is effective and has the potential to investigate and enhance dependability at system level.

“…As an example for options 1 and 2: cooling fans can be used for adjusting the operational temperature, digitally-tuneable power supplies can be used for adjusting the supply voltages, and digitally-assisted electronic systems can be used for reconfiguring or digitally adjusting the performance parameters [Cru09]. Off course, bringing back the operating temperature for complex systems on chip and the supply voltage for battery operated devices to normal operating values will be quite a challenge.…”
