7 years ago --- Quote Start --- The script does not make the pin location assignments for you. All it does is specify the I/O settings (I/O standards, termination, etc.). You still have to assign to specific locations using the Pin Planner. --- Quote End --- Ok, I assigned the specific locations using the Pin Planner. It sill didn't worked. Then I changed the clock input for the DLL PLL from CLOCK_50_B6A (PIN N_20) to CLOCK_50_B5B (PIN_R20) and now fitter completeted successfully. What is the reason for this? Is the PLL DLL too far away from CLOCK input pin? What do I need to do to get the design working with CLOCK_50_B6A? In the working example I can use both clock inputs without problem. Seems to me that fitter fits the design in my project in another way...?
