voltage required for a chip

hi community, what is the required voltage for the Zedboad (7-series), i mean the whole chip? or the minimum required voltage for advanced FPGA?

thank you for replying as soon as possible

regards

Re: voltage required for a chip

@zozo-Please clearly specify which voltage that you are referring? 

 

If you are asking about PL IO banks VCCO then it depends upon IO standards you defined for that bank. The default IO standard is LVCMOS 3.3V. So the default VCCO is 3.3V.

Re: voltage required for a chip

hi @umamahe, thanks for replying, i mean for example in vivado when i designed my architecture so is needing a voltage to work on or we can say to be powerd. i'm talking about all the chip ( all the IPs the maximum voltage that need to work)

Re: voltage required for a chip

Modern FPGAs need several different power supplies. On the Zedboard, you have:

 

1.0V - VCCINT (PL fabric), VCCPINT (PS), VCCBRAM (BRAM)

1.5V - VCC_DDR (RAM interface)

1.8V - VCCAUX (configuration interface), VCCPAUX (PS configuration interface), VCCPO_MIO1 (PS I/O)

3.3V - VCCPO_MIO0 (PS I/O), VCCO_13 (PL I/O), VCCO_33 (PL I/O), VCCO_0 (configuration interface I/O)

VADJ - VCCO_34 (PL I/O), VCCO_35 (PL I/O)

 

VADJ can be set to 1.8V, 2.5V, or 3.3V using a jumper.

 

The Zedboard itself just accepts 12V, which then powers everything else.

Re: voltage required for a chip

Hello @zozo,

 

You can consider using the XPE.

https://www.xilinx.com/products/technology/power/xpe.html

 

You can use the values found from VIVADO after design implementation and put them under the sections given in the excel sheet

to get the power consumption by chip.

 

Hope this helps.

Thank you.
