PLL 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.
