Analog fault modeling (AFM) provides a quantitative measure of quality and insight into defective device behavior. However, the high computational burden typically associated with fault simulation makes it unappealing for industrial applications. We propose an efficient methodology to reduce computational burden of the AFM method by exploiting the hierarchical nature of process variation. We apply...
In many DSP applications (image and voice processing, baseband symbol decoding in high quality communication channels) several dBs of SNR loss can be tolerated without noticeable impact on system level performance. For power optimization in such applications, voltage overscaling can be used to operate the arithmetic circuitry slower than the critical circuit path delay while incurring tolerable SNR...
With the event of nanoscale technologies, new physical phenomena and technological limitations are increasing the process variability and its impact on circuit yield and performances. Like combinatory cells, the sequential cells also suffer of variations, impacting their timing characteristics. Regarding the timing behaviors, setup and hold time violation probabilities are increasing. This article...
In order to realization electronic parts product appearance quality detection control, one kind of processor based on the intelligent knowledge automatic extraction and system intelligence modeling was presented. In the processor, wavelet-fuzzy technique and neural network technique are combined. Uses the fuzzy wavelet extraction image feature, and wavelet function is used as fuzzy membership function...
We present a component-based description language for heterogeneous systems composed of several data flow processing components and a unique event- based controller. Descriptions are used both for generating and deploying implementation code and for checking safety properties on the system. The only constraint is to specify the controller in a synchrounous reactive language. We propose an analysis...
Requirements modeling has been recently introduced in the UML world with the form of a new profile called SysML. This paper explores the possibility to link concepts used to describe requirements with those of the enterprise language of RM-ODP. Some correspondence rules are proposed and illustrated on a case study.
