LogiCORE XAUI v6.0 Core - Incorrect CLK_COR_MAX_LAT and CLK_COR_MIN_LAT Virtex-4 GT11 attribute settings

Description

The LogiCORE XAUI v6.0 Core has incorrect GT11 attribute settings for the CLK_COR_MAX_LAT and CLK_CORE_MIN_LAT attributes. This affects only Virtex-4 GT11 attributes and not Virtex-II Pro MGT attributes.

Solution

To work around this issue, change the following attributes in each of the four GT11 instances in the "transceivers.v(hd)" file: 

 

Attribute......................................Change From.......................Change To 

CLK_COR_MAX_LAT.........................60........................................44 

CLK_COR_MIN_LAT..........................52........................................36
