Peng,

Yes, it works.

If you plan on using OPB_HWICAP it should also be OK dealing with the ICAP itself.

If you plan to write your own wrapper for ICAP then you should know the documentation is incomplete for ICAP, it took me a long time to make it work (using Xilinx web case support and a lot of trial and error).

Hi all,

I plan to make self-reconfigurations on Virtex4 using ICAP. I noticed that the software API of ICAP provided by Xilinx had bugs: "Reading or writing to columns containing SRL16's or LUT RAM's can cause corruption of data in those elements." I don't know have much these bugs may hurt the reconfiguration. Has anyone successfully accomplished self-reconfiguration on Virtex-4 with Xilinx's software platform? Which aspects I should pay great attention for?

Thanks.
