Altera FPGA electromagnetic susceptibility

Hello everyone,

I'm a PhD student and my thesis discusses the safely-use of a FPGA in a highly aggressive electromagnetic environment.

So, I would like to have information about FPGAs critical-level of acceptance from electric field and magnetic field, for example, the CycloneIV ones.

Where could I have these informations ?

These informations are really important for my study. Hope you can help me.

    I believe that susceptibility is mainly a property of the external circuit rather than the FPGA component itself. The FPGA logic thresholds, supply voltage tolerances are determining parameters but they are similar to other digital components.

    @FvM,

    Thanks for your reply.

    I'm not so sure so let's explain a lil bit why.

    Your FPGA, in a standard environment, is weakly subjected to electromagnetic noise, so it works normally, without disturbance. But when you are in an highly-aggressive electromagnetic environment, let's suppose just near an antenna or a radar (lets's be crazy !), the level of the RADIATED electromagnetic noise is not the same and will surely disturbe the execution of your application.

    So what I'm looking for is the critical level of electric and magnetic fields in which the FPGA can work without being disturbed.

    Where I agree with you is that it's certainly a board-level problem regarding CONDUCTED electromagnetic noise.

    Not when it's RADIATED EM noise I think.
