Actually this was my very first implementation, even in simulation it had to be made on boards someday keeping timing skew and capacitance of boards in mind i decided to flip the clock, this will give the control unit a head start of half a cycle and get everything ready before the clock reached the next high, this trick was also used in one of the projects I mentioned at last page in the document. I had to probe and check every signal keeping the standard gate delays of 74 series in equation too!
