Analyse dynamischer Abhängigkeitsgraphen zum Debugging von Hardwaredesigns

Debugging is a time consuming task in hardware design. Thus effective debugging techniques are required when developing complex reliable systems. In this paper a new debugging approach based on the analysis of dynamic dependency graphs is presented. Our approach combines reverse debugging, dynamic forward/backward slicing, as well as spectrum-based fault localization and adapts them for the use on hardware designs. In a case study on two different designs with multiple faults the proposed debugging methodology reduced the debugging time to 50% in comparison to conventional techniques.
