A Standards Based Approach to the Reliability Specification of IP Components
2013Co-Authors: A Evans, Enrico Costenaro, D. Alexandrescu, Michael NicolaidisAbstract:Reliability is a growing concern in complex embed- ded systems. There is an increasing need to understand the failure modes and the overall reliability characteristics of large SoCs which are built using IP components from diverse sources. IP providers must be able to specify the way silicon failures (e.g. single bit upsets, permanent faults) affect the operation of their IP components. This is especially challenging for providers of soft IP because the designs are often extremely configurable and the high-level failure mechanisms (e.g. interrupts, reboots, etc.) must be expressed independently of the underlying Implementation Technology (e.g. FPGA, ASIC, etc.). In this paper, we show how a standard modelling format called RIIF (Reliability Information Interchange Format) can be used to specify the failure modes of complex IP components including a worked example based on a processor core

RIIF - Reliability Information Interchange Format
2012Co-Authors: A Evans, Michael Nicolaidis, Dan Alexandrescu, Enrico CostenaroAbstract:In this paper, a new standard language called RIIF (Reliability Information Interchange Format) is defined which enables designers to specify the failure characteristics and reliability requirements for simple and complex components. This language enables EDA tools to analyze reliability models and to compute the failure rates for complex systems. A formal language makes it possible for suppliers and consumers to exchange reliability information in a consistent fashion and to use this information to build accurate reliability models. The RIIF language is a general purpose reliability modeling language and is not tied to a specific application domain or Implementation Technology.

Low-latency hard real-time communication over switched ethernet
16th Euromicro Conference on Real-Time Systems (ECRTS), 2004Co-Authors: Jork Loeser, H. HaertigAbstract:Ethernet, the most widely used commodity network, increasingly moves toward switches as Implementation Technology thus replacing buses. This allows to use traffic shaping techniques to implement hard real-time distributed systems on commodity networks. However, because Ethernet switches lack build-in policing features, nodes connected by switched Ethernet need to be cooperative. Although the theory behind traffic shaping for real-time communication is known for some time, it has not been considered for Ethernet so far. In this paper, we present the Implementation of traffic shaping on switched Ethernet Technology. We make thorough experiments to understand the cost and practical limits of using fast and gigabit Ethernet for hard real-time communication. We do measurements to analyze properties of switches and delays that we can achieve using these switches. We further analyze the influences of non real-time Linux nodes sharing the network.
