Does FPGA performance reduce after multiple cycles of reprogramming?

Does FPGA performance (max stable clock speed) reduce after many cycles of programming?

Solution

  • It depends on the technology of your FPGA.

    There are 3 technologies available:

    Antifuse: Can be programmed only once, so I think you are not talking about them.

    Flash: As Every flash, the number or reprogram is finite, but until it stops to work (aka can't write the flash), there is no degradation of speed

    SRAM: This one can be "infinitely" re-programed. Now as every electronic component, it will decay with time and overheating, but it is not really related to the reprogrammation
