Continuous interface access to device-level primitives in reconfigurable devices in extreme environments is key to reliable operation. However, it is possible for a primitive's interface controller, which is static to be rendered non-operational by a permanent damage in the controller's circuitry. In order to mitigate this, this paper proposes the use of relocatable proxy circuits to provide remote interfacing capability to primitives from anywhere on a reconfigurable device. A demonstration with device register read controller shows that an improvement in fault-tolerance can be achieved.
