RE: https://infosec.exchange/@PagedOut/116362415442678434 This article (recommended if you're learning RE!) reminded me of a GOATed FPGA bistream reversing task from Google CTF (GPURTL by Robin), where the key to solving it for me was observing the pattern of changing bits in FPGA's registers. The pattern itself was enough to pinpont the exact algorithm. @liveoverflow made a video about this task: https://www.youtube.com/watch?v=3ac9HAsfV8c
