current measurement on FPGA

[Billel]

Hi 

i'm using Atlys and basys3 FPGA. Are there a possibility to measure the current flowing out of the FPGA in order to determine the real power consumption.

best regard

Hello,

You can measure the current on Atlys using LTC248IC with I2C communication. Please see the last page from the schematic:

https://reference.digilentinc.com/_media/atlys:atlys:atlys_sch.pdf

 You can find the datasheet for that component on the following link: http://cds.linear.com/docs/en/datasheet/2481fd.pdf

Unfortunately this cannot be done on Basys3 because there are not some similar components for current measurement. 

Regards,

Cristian

Hello Cristian

first of all I want to thank you for your reply.
So, is the LTC2481C already Implemented on the Atlys Board?

no solution for the Basys3?

thanks

Hello,

Unfortunately we don't have a HDL component for LTC2481C.

On Basys3 you could measure the current with a multimeter but you should modify your board and we didn't recommend this.

hello Cristian.

i just order a Genesys 2, according to the Datasheet we can measure the current, can you guide me on how to do it? 

Thank you
