Abstract
Approaches are disclosed for processing a circuit design to protect against single event upsets. A logic path of the circuit design is selected for redundancy based on a total of failure rates of circuit elements in the logic path being greater than a product of a target reduction in failure rate of the logic path and a failure rate of a voting circuit. The circuit design is modified to include at least three instances of the logic path coupled in parallel and a voting circuit coupled to receive output signals from the instances of the logic path. The modified circuit design is stored in a memory.
