Hello Luis Angel,

The uhd_image_builder was written in order to ease this process. Seeing
that you used it successfully, it makes me wonder: is there a reason that
you mind sharing with us on why do you want to go around the script? I ask
in order to, maybe, identify a need that could added into the script and we
have been overseeing it.
So, you modified the rfnoc_ce_auto_inst_x300.v, which is the way to go.
But, how did you afterwards start the synthesis? This step might be the
reason why you did not see the any blocks. Actually, "not seeing any block"
is certainly something that is not supposed to happen (I would dare to say
that it is something that just won't happen, becaused of the way the
synth/build system works). Maybe you mean that you saw blocks but not the
ones that you expected? If this is the case, which blocks did you see? This
could also indicate what kind of image you synthesized/build.
Another thing: in earlier emails you mentioned that you were using the X310
device. Keep in mind that rfnoc_ce_auto_inst_*x300*.v and
rfnoc_ce_auto_inst_*x310*.v are two different files. If you modified the
*_x300.v version and then built the X310_RFNOC_* target, that would explain
why you are not seeing your block.

You have to modify the rfnoc_ce_auto_inst_x300.v (or the *_x310 version,
depending on your device) and have all your custom files being accesible by
the build system by adding them to the Makefile.OOT.inc. After that, just
build the target with:
$ make X300_RFNOC_HG
or the X310 version of the target, or the other HLS/XG version. If you only
want to have the FPGA image, you don't need the Vivado GUI. If you need the
Vibado GUI for any other reason, just add "GUI=1" to the make command.
Or you can use the image_builder, or its GUI version, to help you around a
bit on this.
