I'd go one step further, and just have a massive cartesian grid of 4x4 Look Up Tables (LUTS) clocked in a checkerboard manner... all of one color is active, then all of the other color... it prevents all race conditions. There are HUGE advantages to computing this way, in terms of relocating code, routing around defective cells, security, etc. I've blogged about it at length in the past.[1] [1] https://bitgrid.blogspot.com/ https://bitgrid.blogspot.com/
