Honored ContributorI have considered trying that, but am trying to save it as a bit of a last result. The gxb block is assuming that the input it's receiving (the bitstream from the SFP receivers) has already been 8b10b encoded, so if I were to bring the receiver output directly to a pin, it would be after going through the 8b10b decoder (which is internal to the block created by the gxb mega function, and as such to my knowledge unaccessible), which would require me to have either a good enough understanding of 8b10b encoding to decode the test input by hand or a tool for automatically decoded 8b10b messages, both of which I unfortunately do not have :(
Thank you for the suggestion, though. I'm hoping to avoid getting too deep into the actually encoding/decoding schemes that GIGE uses, but it looks like that might just be an unavoidable consequence of working with the things. -Jordan Wills
