Abstract

As the trend in reconfigurable electronics goes towards strong integration, FPGA devices are becoming more and more interesting. They are already used for safety-critical applications such as avionics [9]. Latest FPGA's also enable new techniques such as dynamic partial reconfiguration (DPR), allowing new possibilities in terms of performance and flexibility. Their use in safety-critical systems is considered as impossible nowadays since they must be strictly validated, and DPR brings many new issues. Indeed, the tools used for DPR must be certified, which is barely impossible for the current DPR tools provided by the vendors. We have developed a simple flow upon the usual static one for Xilinx FPGA's that does not require any support of the vendor tools for DPR. This lessens the complexity of tools certification, and make a step towards enabling the certification of DPR for safety-critical applications. Moreover, under strong hypotheses, and by using safe design principles, we show how the complexity of certifying DPR can be reduced.
