SEU TEST –Use 32-bit counter generate data, –Serialize the data by PISO S.R., then shift the data through the chain of SISO S.R. –Deserialize the data to reconstruct to the result of the 32-bit counter. –Add 1 and store the data, then comparing with the next coming 32-bit data. –The differences between the two data is considered as the result of the SEU, and count the number of SEU. –Count the total number of data and calculate the SEU percentage. –Use 32-bit counter generate data, –Serialize the data by PISO S.R., then shift the data through the chain of SISO S.R. –Deserialize the data to reconstruct to the result of the 32-bit counter. –Add 1 and store the data, then comparing with the next coming 32-bit data. –The differences between the two data is considered as the result of the SEU, and count the number of SEU. –Count the total number of data and calculate the SEU percentage.

PISO Shift Register → Barrel Shifter In the document, it is said that “The LSB is loaded with Shiftin”. We also contacted with Actel, but no response… So we use barrel shifter instead of the PISO S.R. –We could use B.S. as the serializer, but it decreases the speed of test. –In the simulation, we meet another question.
