Virtex-6 (ML605) Jumpers on J35

Jump to solution

 

When I got the ML605 board the jumpers were positioned as shown in the picture below. Should I assume that they are on pins 1-3 and 2-4? Do I need to leave either of them there or can I move them to 9-11 and 10-12? But page 10 (UG533.pdf) says that the default jumpers settings are on 9-11 and 10-12.

Also, when I try to measure the power in System Monitor I am interested in the voltage, current, and power for the board and core.

 

I understand that board voltage is as follows:

board votlage: aux[12]

board current: aux[13]

 

But which pin is for core current? It seems like it would be V_P/V_N not one of the AUX[1-16]. Is that right? Is the following figure from UG370 pg. 60 just using external power source and resistor?

 

Also, do I need to set up system monitor in my designs if I want to use it to measure power or will it always be set up properly if I don't change it? I am just a little confused and don't want to screw anything up, so thanks for the help.

Yes.

 

In the future, the contents of this AR (#41818) are applicable to almost any device for locating pin 1.  Coupling that with the schematics or UG diagram will get you which pins are which every time.

Can you please tell me the serial number of your board?

 

In the meantime, follow the User Guide's recommendations for the default settings as those are correct.

S/N: 1212-1155

 

So I should assume the jumpers are on 1-3 and 2-4 right now and I can move them to 9-11 (bottom left) and 10-12 (bottom right) without causing harm to the board?

Ah, that is a great way to be sure. But according to the square pad, pin 1 is the bottom right pin, so the jumpers are already on 9-11 and 10-12. This would mean that I should not move them. Do you concur?

 

Does the documentation just assume that I have the board the other way around?

The schematic is orientation agnostic.  That diagram in the UG was pulled from the schematic.

 

Best of luck!

Good to know. Thanks!

 

Then for core current I can measure on V_P/V_N not one of the AUX[0-15]. Is that right?

How do we determine the shunt resistor values for the board current? Where would it be in this schematic: ml605 ?
