Abstract
Self Restoring Logic (SRL) provides for SEU tolerance in high speed circuits. An SRL cell is designed to be stable in one of two internal states. Upon an SEU event, the SRL cell will not transition between the internal stable states and recover from an SEU. SRL circuits are realized with SRL storage cells driving succeeding SRL storage cells directly or through combinational logic such that the corruption of any one internal state variable in the driving SRL cell and it's the associated combinational output logic can affect at most one internal state variable of the succeeding SRL cell. An SRL circuit does not allow propagation of single SEU faults.
