core voltage analysis after dumping the logic into LABs

Hi

I am trying to analyze the core voltage behavior in Cyclone-III FPGA. I want to check the core voltage behavior after dumping the logic into different LABs in Cyclone-III FPGA and using a different core voltage supply for each core voltage pin. If iam changing the LABs location the voltage of power supplies are changing but i am not be able to differentiate the core area that if i am putting the design in a specific area then it will take the power or current from a perticular supply.

so if anybody is having a these type of results plz send it to me.

thanks.
