New ContributorPLL not working on 10M16DCU324 FPGA_Quartus toll
Hi,
As mentioned by FvM, according to the Pin Connection Guideline, you must connect all the VCCD_PLL pins 1.2V power supply. So I think your understanding is correct: you have to connect all the VCCD_PLL pins to power supply to make sure the PLL works normally on 10M16DCU324.
By the way, it seems you were trying to migrate the 10M02 board to 10M16. By comparing the Pin-out of 10M02DCU324 and 10M16DCU324, you can see there are multiple different pins, including GND, VCC, VCCA, VCCD_PLL and some VCCIO. Please also check if these pins are correctly connected for 10M16 as well.

New ContributorI tried with my 10M08 FPGA device and it is working there, where only VCCD_PLL1 and VCCD_PLL2 is connected to 1.2V. It might be working as there are only 2 PLL modules for 10M08 keeping NC for PLL3 and PLL4.
I tried with my 10M16 FPGA device and it is not working there, where only VCCD_PLL1 and VCCD_PLL2 is connected to 1.2V. It might not be working as there are 4 PLL modules for 10M16 and i made NC for PLL3 and PLL4 VCC pins.
Is my understanding correct?
