Honored ContributorI've tried to do it on Cyclone III devices with Quartus II ver. 7.2, but the results are exactly the same... but as You wrote the problem is probably in pin assigments as I thought too. I'll try to find in documentation what pins are exactly for PLL.... because till now I did it without changing pins... just the graphical schematic then compilation and simulation... I'll write how it works :) Thanks for help
--------------------------------------------------------------------------------------------- .... I set the pins manually without trusting the automatic fitter and it's much better. Of course this is just the simulation but better simulation = better working in real .. :)
