Essentially, what we are trying to do, is drive a pattern out
from an FPGA, through the ADV7511 HDMI xmtr and off the board, then wrap that
around back onto the board, through the ADV7842 HDMI rcvr and back into the
FPGA to capture the pattern.
We'd like to do this with as small of a data set as possible. We are not
trying to perform a functional test, just test all the signals on the board
structurally (e.g. opens/shorts). Is there a mode we can put the xmtr and rcvr
in that will allow signals to pass through, but without haveing to provide
valid video formats?
