XC7Z030 bank 35 power supply problem

Hi,

 

I'm testing a custom board which uses a XC7Z030, I try to configure device using iMPACT.

 

But I get error: 

 

ERROR:iMPACT:585 - A problem may exist in the hardware configuration.

            Check that the cable, scan chain, and power connections are intact,

            that the specified scan chain configuration matches the actual hardware, and

             that the power supply is adequate and delivering the correct voltage.

 

I checked the schematic and found that the power supply for bank 35 of XC7Z030 is 3.3V, this is wrong because bank 35 of XC7Z030 is High performance bank, which allows maximum 1.8V power supply.
I affraid the XC7Z030 is damaged but have no method to check it. 

My questions:
1. How many percent XC7Z030 is damaged when bank 35 power by 3.3V?
2. Is there any way to check if XC7Z030 dead or alive?


Please give me some advices
Best regards,
conghong

Re: XC7Z030 bank 35 power supply problem

is there any possibility in your board to change the bank35 voltage to 1.8v and see if the device is functioning?
