Virtex/Virtex-E/Virtex-II/Pro - How do I calculate MTBF reliability numbers for devices? What is the expected lifetime of a Xilinx FPGA?

Description

Keywords: MTBF, Virtex, 4000, FIT, reliability, Virtex-II, Pro, life, span

How do I calculate/find MTBF reliability numbers for devices? What is the expected lifetime of a Xilinx FPGA?

Solution

FIT rates for Xilinx devices are published in the Device Reliability Report
http://www.xilinx.com/support/documentation/user_guides/ug116.pdf

To calculate mean time between failures (MTBF), use 1/FIT.

NOTES:
1. The reliability stress tests are conducted according to the conditions specified at JEDEC Solid State Technology Association's reliability test methods for packaged devices, JESD22, except Group B and D tests in which it follows DSCC's test methods, MIL-STD-883.

2. Reliability-based testing and related data published does not apply to engineering samples (ES parts).
