Quartus used to report the min and max pll input frequencies in the PLL Usage Summary report. Where is that information now?
I have a source synchronous design there the transmitting device can have a different clock rate depending on some settings. I need to know my switch over points for PLL reconfiguration and I need to come up with a minimum number of settings to cover my desired range.
Yes, Quartus does not report the Minimum/Maximum lock input frequency for the PLL.
However we have to manually calculate it.
Fin min = VCO min frequency x N / M x C
Fin max = VCO max frequency x N / M x C
C/K is Post-scale counter.
For VCO min/max frequency refer respective device Datasheet.
Please go through below KDB link for more information.
