I'm puzzling over the how it seems like some shuttle entries are configured in the harness: it looks like all the pads are mapped to the harness which MUXes out access to them from the user area (while also buffering them). For the projects that work with high frequencies (like the 2-4GHZ VCO in the satcom project)... are they interfacing through these MUXes/buffers or is there something I'm missing?
