Outil de CAO pour la génération d'opérateurs arithmétiques auto-contrôlables

Abstract : With the increasing integration density, new generations of integrated circuits are becoming more and more sensitive to noise sources such like power line disturbances, electromagnetic influence, etc.Further, it is now proved that some particles coming from the space (alpha particles and atmospheric neutrons) can also interfere deep sub-micron circuits
operation (soft errors). Face to this challenge, self-checking techniques could provide good solutions. A good solution must of course result in
reduced hardware overhead cost and little or no performance penalty. At that stage, two global difficulties appear. First, self-checking techniques are known by a restricted group of designers, and second, there are
no professional CAD tools for automating self-checking circuits generation. In this work, we show that self-checking multipliers based on residue codes can result in a very
little hardware overhead, especially for large multipliers. In a second time, we generalize fault secure solutions for multipliers, adders and shift registers based on the parity code. The new versions have several parity bits in order to increase fault coverage. We have implemented the presented solutions in a CAD tool developed by our research group.
This tool offers many different self-checking arithmetic and logical operators to make flexible the construction of self-checking data paths.
