Exploiting Modified Placement and Hardwired Resources to Provide High Reliability in FPGAs

Possible scenarios for future manufacturing technologies increase the desirable features of fault tolerance techniques, such as coping with multiple faults and reducing error latency. On the other hand, current high-end FPGAs present, besides lookup tables and flip-flops, several dedicated components that perform the most commonly required functions. In this paper, we propose an approach to use such resources to efficiently provide fault detection capabilities. We further extend the technique with placement constraints to enhance the detection of faults affecting the routing resources, which is a critical demand for such devices.
