Problem with Fitter LL Ethernet 10G R core rx/tx_serial I/O

[MSenk1]

Hallo,

I'm using the LL Ethernet 10G R core from Intel.

When I use the sample design it works fine.

When I start adding more functions after a while the fitter (Quartue 21.2/3)gives me this error message:

Error(16297): An error has occurred while trying to initialize the plan stage.

I started several times from scratch but after a while I get this error message and I found not way to return.
