12.2, Spartan-6, IBERT - IBERT core takes a long time to come up after configuration


After I configure a Spartan-6 device using 12.2 or 12.3 IBERT, it takes a long time before the IBERT core is recognized in the ChipScope analyzer.


In 12.2 and 12.3, it can take up to 40 seconds before the analyzer tool recognizes the IBERT core on your part.
This is a known issue andis scheduled to be fixedin the next version of the software. In themeantime, you need to wait until the IBERT core is recognized by the software, as this performance issue does not affect the functionality of the core.
Please note that this only affects the IBERT core generated in 12.2 or 12.3 when using Spartan-6 devices. The problem is not exibited on Virtex-6 devices.
