Abstract
We propose a measurement architecture that allows to trace generation and propagation of single- event 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 ex- hibits both properties we are interested in, namely di er- ent amounts of fanout and a carry propagation chain. The problem of devising a suitable on-chip measurement infras- tructure lies in the partly contradictory requirements, like constrained area, radiation tolerance and good resolution of the location and propagation path of particle hits. Our pro- posed architecture is based on linear feedback shift registers that can be used as lean and robust counter implementa- tions. 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.
