Hi,

 

I use the test bench FMCMOTCON1-EBZ with the reference design hdl_2014_r1

 

 

i want to measure the motor current ia,  ib from the XADC Measurement Signal chain.

For this i use the ila-core in VIVADO and the signals from axi_mc_current_monitor_v1 ia_o[17:0] and ib_o[17:0].

But I don’t know how to convert the value into the unit ampere.

 

for example I have the value ia_o [18Bits]: 000000010111100000 in my ila-scope.

 

Thanks

Steffen
