 FPGA's suck at random logic, my cpu speed has dropped from 20 Mhz to 15
when I added my control section - random logic -.

I say it is NOT, because at those speeds you still have to place it by
hand anyway. Here is a good link to prove that point. Mind you some the earlier chips were prone
to meltdown - they ran too fast. What is the problem is you have
in the modern machines - nothing like a PDP-n that had a nice simple
logic and control design.
