1) How do I calculate/find MTBF reliability numbers for devices?
2) What is the expected lifetime of a Xilinx Device?
1) FIT rates for Xilinx devices are published in the Device Reliability Report:
https://www.xilinx.com/support/documentation/user_guides/ug116.pdf
To calculate mean time between failures (MTBF), use 1/FIT.
