Hi There,
I have a pretty simple 4-layer board with strange ESD problems. Using a ESD gun and shocking the frame-ground terminal of the power terminal block the FPGA configuration will sometimes get corrupted. I'm stumped because, as far as I know, the goal of ESD protection is to get the charge to frame-ground which is what I'm doing but it still causes problems. I do have separate frame and digital ground which I tried connecting with caps or resistors with equally disappointing results
Any idea what could be causing this ?
Thanks in advance
