Changing loopback mode of GT in MRMAC

Jump to solution

I am trying to do Near-end PMA loopback on MRMAC. As MRMAC doesn't provide direct port to configure it, I output a signal from cips to control the SW_REG_GT_LOOPBACK in PL. But then the timing constraints won't meet. 

So do you have some good solutions to control the loopback mode in MRMAC?

Hi @RuashTime ,

The loopback should not impact timing I believe. Do you have more details regarding this? 

Is this related to pma near-end loopback question you ask in another thread/SR?
