Design, Automation and Test in Europe Range Based Analysis of Inner Systems Characteristics (extended Abstract for the Edaa/acm Sigda Phd Forum at Date 2015)

The design of embedded systems faces new challenges in increasing functional density and decreasing silicon structural sizes. With the consequence that variations of circuit parameters, input signals, manufacturing processes, etc. from its ideal may cause an increased parasitic impact on the full system behavior. The main research topic within this work is range based simulation and analysis of electronic designs where system parameters are superimposed by random uncertainties. Introduction and Motivation Variations in circuit parameters and model characteristics have to be considered from a very early stage in the design process. Uncertainties may be caused by: → Abstraction of models → Process variations and manufacturing abnormalities → Deviated signals (time/frequency domain, analog/digital) → Unspecified user operation, etc. Uncertain Signals and Parameters Mixed Signal System Design Sensitivities Behavioral Impact Internal Effects ...?
