Agilex 9 power

We started a new design based on the Agilex 9

AGRW027R28A2I2V

Our power designer has the following question:

"Can the VCCA_AXA0_1P8 and VCCA_AXA1_1P8 be powered by the same voltage regulator or does each rail need its own separate voltage regulator?
Same with the VCCA_AXA0_1P2 and VCCA_AXA1_1P2, and for the VCCA_AXA0_0P9 and VCCA_AXA1_0P9."

Any insight or experience tying these rails together you can share will be helpful.

Thank you

Power

    Hello, 

     

    It is recommended to separate the power to maintain the signal stability for analog components of the FPGA. VCCA_xxx is supplying power to analog blocks of the FPGA(PLL, transceivers etc.)
