We have a system with a 100G CMAC and works as expected, CAUI4 PCS, 100G MAC, RMON state, etc. all good. Unfortunately I'm trying to use the CMAC OTN Rx Interface but can't get any sign of life out of it; according to the documentation the outputs signals are always available, I've hooked up ChipsScope to:
and all signals are stuck (I use the rx_clk to sample the signals as described in the UserGuide). I've also connected those signals to debug registers and nothing, has anyone used this interface successsfully?
Thanks in advance,

Please try IP core example design first.
Can you see them working in the example simulation?

Good call on the simulation, now this gets interesting... so there is activity on those signals in simulation but in HW they are stuck regardless of the input I feed into the CMAC, whether is a valid CAUI4, unframed 100Gbps, etc. Any other suggestion would be apreciatted.

Have you tried the example on board?
How is stat_rx_aligned and stat_rx_synced on board?
