BUFG usage of pcie core

hi all,

 

According to pg23, 3 BUFGs are used for PCIe Gen3.

But that's true only for 2014.2. In 2014.3, the gt_wrapper will initialize 4 bufgs. How to eliminate those BUFGs?

 

regards

Hi,

 

In 2014.3, there is a problem in GT that got fixed.

http://www.xilinx.com/support/answers/59294.html

 The implementation that was given resulted in a per lane BUFG usage.

I belive this got fixed in 2014.4. can you check it ?
