What are you doing with a Xilinx bitstream even if you have it besides producing more of the device without authorization? How exactly are you analyzing it for any meaningful information? It's absolutely not "easier" to attack an FPGA in this manner because the information yielded isn't something a smart fellow can just pop into IDA and glean every secret from: it's a highly optimized gate configuration with massive amounts of redundant register, LUT, etc. insertion. All structures resembling "code" are gone. You'll never see RTL from this information and there's nothing like assembler for it. All of this is assuming that the nation state actor can keep the device powered while doing this extraction, because once that voltage drops even a couple hundred mV below the allowed value, that bitstream is gone. Tamper switch, timer, batteries dead, a 30 cent microcontroller analyzing environmental conditions, velocity, etc. and cutting the power: it's gone forever.
