Scrubbing via JTAG on commercial Virtex 5

Hello,

 

I'm reading XAPP 1088 about correcting SEUs on Virtex 4. It appears to me that the Application Note only refers to scrubbing on SelectMAP interface.

 

Now, I should perform scrubbing on a Virtex 5 FX130T device which is only connected via JTAG (in a daisy chain to both impact on a host PC and a ROM holding the original bitstream). Is it possible to perform scrubbing over JTAG?

 

Thanks a lot

@giorgio.lopez Yes it is possible.

 

 

The fundamentals of implementation are the same for all interfaces with JTAG.

But what is the procedure? I can't seem to find any documentation. Moreover, it looks like with the procedure explained in XAPP 1088 you can perform scrubbing without interrupting functionality of the user design, while I think that using JTAG does.
