Certification of FPGAs-Current Issues and Possible Solutions

• This paper looks at possible applications of Field Programmable Gate Arrays (FPGAs) within the safety critical domain. We examine the potential benefits these devices can offer, such as parallel computation and reconfiguration in the presence of failure and also the difficulties which these raise for certification. A possible safety argument supporting the use of basic reconfiguration facilities of a reprogrammable FPGA to remove Single Event Upsets (SEUs) is presented. We also demonstrate a technique which has the potential to be used to identify areas which are sensitive to SEUs in terms of safety effect, thus allowing optimisation of an FPGAs design and supporting our argument.
