I'm using a 16500A (rather than a B, C, or 1670x) because it should be much simpler to figure out how the processor accesses the registers and memory of the modules. Then it should be possible to build something like a USB4 PCIe alternate mode interface to the analyzer backplane, replacing the analyzer's CPU card. I don't intend to reverse-engineer details of how the modules actually work. Instead, I want to run the real 16700 software in simulation or binary translation on a PC. The tricky part is going to be figuring out how the module correlation circuitry on the CPU board works, because my plan requires reproducing that.
