Estimating the SEU failure rate of designs implemented in FPGAs in presence of MCUs

In this work, bitstream based SEU emulators are updated to consider MCUs. It is discussed the necessity of injecting faults on physically adjacent cells, in order to emulate appropriately the effect of MCUs. Adjacent MCU injection has been compared theoretically with an approach considering MCUs as bunches of independent SBUs, as it is done in other emulation platforms. A Zynq-based fault injection platform has been used, in order to apply this way of emulating MCUs and validate the proposal.
