I can rout differentially these signals J31 / 8-10 / ab, but from recomendation they should be GTP or CC.
The RTM_CLK (which from recomendation is AMC_CLK ) actually goes to cross-bar
Another one is is "RTM_ADC_DAC_SYNC.SYNCOUT11" and it is possible to route it to cross-bar, but please pont which input I can use to make it useful
The plan for RTM in AFCZ was to eventually replace the Sayma AMC. But for the moment it's not important
Up to my understanding, GPTs are just transceiver clocks. In Ultrascale architecture, it is possible to also output signal from the REFCLK pin pair. See #37.
Regarding compatibility - I think generally it would be better to stick to the standard. Even if it's not that widespread. Especially if it does not cost us that much (like f.e. in case of AFCv4).
J31 / 8-10 / ab
do not follow the recommendation, evaluate the possibility of keeping currentRTM_FPGA_CFG
as an assembly option while routing proper signals to these ports
