Readbackn on Virtex II Pro devices

[Nick]

Hi everybosy,

I was wondering whether the distributed/block selectRAM+ readback
facility can be perfomed on a single block at a time, or does it have
to be performed on all blocks?

Similarly, can the memory configuration read back be performed in
sections or does it have to be done on the whole memory?

Thanks

Nick

Nick,

Readback is performed on a frame basis. A Column, (CLB/IO/BRAM) contains
many frames, and a frame covers many CLBs (or LUT RAMs if you line them
up vertically). Please take a look at XAPP138/151 for more information.

Regards, Wei
