A cost-efficient framework for executing life-time dependability procedures is presented in this paper. The proposed framework relies on distributed sensors and actuators (embedded instruments) for self-awareness and adaptation, where the IEEE 1687 standard (iJTAG) is utilized for the dependability communications and the on-chip access of the instruments.
Interconnection reliability threats dependability of highly critical electronic systems. One of most challenging interconnection-induced reliability threats are intermittent resistive faults (IRFs). The occurrence rate of this kind of defects can take e.g. one month, and the duration of defects can be as short as a few nanoseconds. As a result, evoking and detecting these faults is a big challenge...
In this paper, functional unit-based IDDT testing has been applied for a 90nm VLIW processor to monitor its aging degradation. This technique can provide health data for reliability evaluation as used in e.g. prognostic software for lifetime prediction. The test-program development based on the architecture of a single DSP processor, as well as implementation of an accelerated test (AT) is investigated...
An embedded health-monitoring infrastructure for a highly reliable MP-SoC for data-streaming systems is presented. Different from the traditional approach of a dependable design, our infrastructure is based on life-time prognostics from health-monitoring sensors that are embedded near the target processor. This enables the preventive repair by spare parts or priority ranking of tasks among processors...
A new generation of highly dependable multi-processor Systems-on-Chip for safety-critical applications under harsh environments with zero down-time is emerging. In this paper1, the approach towards reaching this ultimate goal is explained. Crucial is this method is linking the measurement data of so-called (on-chip) health monitors during life time with the measurements of degrading key performance...
The semiconductor industry for automotive applications is growing rapidly. This is because advanced electronics is now being developed to monitor and control many vital functions previously handled purely mechanical. In addition hybrid and pure electrical cars are emerging. Parts of these electronic systems have strict safety-critical requirements, while operating in a harsh environment. Although...
