Hey People, I have been using the DE2 board for a while now with the nios processors and my own designs. I was wondering if anyone could help me with this PLL Problem. I have a one PLL with 3 st...

18 years agoThe warnings aren't related to PLL operation in general, they can be ignored regarding phase shift.
I would expect, that the phase shift is implemented as shown in the schematic symbol, however, the actual PLL parameters can be reviewed in compilation report under fitter/ resource section/PLL. I can't see how the phase shift can be vizualized by dividing the clock, cause this operation doesn't increase the ns scale of the phase shift. But it would be detectable with a fast multichannel oscilloscope.
