current measurement on Genesys 2 board

[Billel]

Hello All

I recently got my Genesys 2 fpga board, and I need to measure the current flowing out of the FPGA in order to determine the real power consumption of my design. is it possible to use Adapt like in the older version of Genesys? if it's not, is there any tutorial on how to do it without ADAPT?

Hello,

You can measure the current using INA219AIDR with I2C communication. You can see the connections between the INA219 and the power sources on page 21 from the schematic: https://reference.digilentinc.com/_media/genesys2:genesys2_public_sch.pdf

Also you can find the SDK library in ...\demo\sdk\demo\src\INA folder from the Demo archive: https://reference.digilentinc.com/_media/genesys2:genesys2_release.zip

INA219AIDR datasheet: http://www.ti.com/lit/ds/symlink/ina219.pdf

Thank you Cristian

Hi, 

I was wondering what setup I need to do (tools, software I need) to do run-time monitoring of power consumption (using I2C interface). I currently use xadc and ilacore to monitor internal signals and temperature of pga and log their values using tcl command in vivid hardware manager. Any suggestions ?

 

Thanks

Hi Rana

Are you using a Genesys 2 fpga board? If yes, are you using a Microblaze as a soft-core?

I have done a current measurement on Genesys 2 FPGA but using a Microblaze.
