Successful use of MGT on Virtex 4



Has anyone been able to successfully simulate a test of the MGT on the
Virtex-4? I've been trying to instantiate the GT11_custom for a while,
and it just does not seem to work. Basically I've instantiated two
MGT's and have tied them together via the RXN/P - TXN/P. I've tried to
use 8B/10B encoding and that didn't seem to work. This lead me to
strip the MGT completely and use it only as a SERDES device, yet it
still does not seem to work. (Assuming that whatever data I send on
TXData_IN is what should be on RXDOUT.)

I've been told to try the Aurora primative and I've followed the
"Getting Started" document and it will not simulate using a Virtex-4.
However, if I choose a Virtex 2 device, such as in the example
document, then it simulates fine.

Is this an issue with the Virtex-4?

If anyone out there has ever got the Virtex 4 to simulate the MGTs, can
you please help me?

Thanks,

JP
