Hello,
I'm trying to add a Xilinx DDS to a custom RFNoC block (using UHD 4.0 and
associated gr-ettus repo). To do this, I started building the FPGA image using
the GUI option, stopped the build shortly after Vivado opened, and saved a
Vivado Project. Then, in Vivado I configured/added a Xilinx DDS to my custom
RFNoC block hdl and built the project just fine.
Now, I'm trying to setup my build file structure so I can use the "make" flow
to build the FPGA image. I've tried several things.
1) I copied the xci file directly to my rfnoc/fpga/rfnoc_block_Block folder.
Then, I added the following to the Makefile.srcs file in the same folder:
RFNOC_OOT_SRCS += $(addprefix $(dir $(abspath $(lastword $(MAKEFILE_LIST)))),
rfnoc_block_Block.v noc_shell_Block.v rfnoc_jjj.v DDS_Test_Signal.xci)
When I try to build the FPGA image, I get the following critical warning:
CRITICAL WARNING: [Vivado 12-1504] The IP is already part of the fileset
'sources_1'. Requested source
'/home/XXX/Projects/SCISRS/usrp/gnuradio/3.8.2.0_uhd4.0.0.0/src/RFNoC_Custom/rfnoc-peanut/rfnoc/fpga/rfnoc_block_Block/DDS_Test_Signal.xci'
will not be added.
followed by these errors:

2) Looking at the rfnoc-example included under uhd/host, I see that this
comment is in Ettus's /rfnoc-example/fpga/Makefile.srcs file:
# If there are additional modules or IP (other than what is in the RFNoC block
# subdirectories) that needs to get installed in order to synthesize blocks from
# this module, list them here:
#RFNOC_OOT_SRCS += $(abspath $(addprefix ${RFNOC_EXAMPLE_DIR},
#my_other_module.v \
#ip/my_ip_core/my_ip_core.xci \
#))
So, I created an rfnoc/fpga/ip/DDS_Test_Signal folder and copied the xci file
there. Then, I added the following line to my /rfnoc/fpga/Makefile.srcs:
RFNOC_OOT_SRCS += $(abspath $(addprefix ${RFNOC_EXAMPLE_DIR},
ip/DDS_Test_Signal/DDS_Test_Signal.xci))
When I do this, I get:
Environment successfully initialized.
BUILDER: Checking tools...

So, I'm obviously not adding the IP correctly. Can anyone point me in the right
direction?
Thanks,
Jim
