5.1i BitGen, Virtex-II - DCI does not work correctly in certain circumstances (poorly matched DCI termination)

Description

General Description:  

BitGen does not correctly configure the IOBs for DCI in banks where only differential DCI I/O standards are used.  

 

Banks that contain any single-ended DCI I/O standards are not affected by this problem. Designs with this problem will exhibit poor impedance matching on differential I/Os terminated with DCI, and poor signal integrity will likely result.

Solution

This problem is fixed in the latest 5.1i Service Pack, available at: 

http://support.xilinx.com/support/techsup/sw_updates
The first service pack containing this fix is 5.1i Service Pack 1.
