Way back at the start of your work on 625 to 405 conversion you were connecting the sync outputs of your decoder to the logic because you were worried about implementing a digital sync separator. In the end the digital sync sep was no problem.
When I designed the hardware I'm using it was many years(15?, 20?) ago and for a professional client. I planned to use a digital sync separator but I had some spare connectivity available. So I thought it would do no harm if I hooked up a few of the odd sync etc pins on the SAA7118 decoder to the FPGA. You never know, I thought, there may be some function I'll need for a different project on what was designed as very flexible hardware. I have never used them before but now might be the time I need them.
