We propose a measurement architecture that allows to trace generation and propagation of singleevent transients in a combinational target circuit that will be subjected to radiation in an experimental study. We choose the Sklansky adder as a target circuit, since it exhibits both properties we are interested in, namely different amounts of fanout and a carry propagation chain. The problem of devising a suitable on-chip measurement infrastructure lies in the partly contradictory requirements, like constrained area, radiation tolerance and good resolution of the location and propagation path of particle hits. Our proposed architecture is based on linear feedback shift registers that can be used as lean and robust counter implementations. These counters are attached at selected locations within the target adder circuit, and we show by means of a simulation study as well as a fault dictionary that this architecture indeed comes up to our expectations.
