AR# 38340: 12.x ChipScope Pro, IBERT, Virtex-5, GTX - Line rate is displayed incorrectly and links are down
12.x ChipScope Pro, IBERT, Virtex-5, GTX - Line rate is displayed incorrectly and links are down
I generate my IBERT GTX core with a 32-bit data width and 2.0G line rate. When I pull up the Analyzer, the line rate is detected from the divider settings as 2.5G, and all the links are down. What is the issue here? How can I get the links to work?
The INTDATAWIDTH port is improperly set to 1 (div by 5) when it should be 0 (div by 4). Setting that value manually in the Port settings tab causes the channels to immediately link. This issue is resolved in ChipScope Pro 12.4.
