Issue Description

I get the following error when building my custom OOT module with custom rfnoc blocks

ERROR: [Synth 8-439] module 'axi_intercon_2x64_128_bd' not found [/workspaces/rfnoc-my_oot/build/ip/xc7k410tffg900-2/axi_intercon_2x64_128_bd/axi_intercon_2x64_128_bd_wrapper.v:384]

Setup Details

UHD 4.7.0.0-210-ge75629c3 in a Ubuntu 22.04 docker image

Expected Behavior

Not to have this error

Actual Behaviour

I get this error

Steps to reproduce the problem

1. Create new oot with rfnoc_modtool
2. Copy gain example's yaml file
3. Replaced the name gain with my block name
4. Added xci files that I already made to rfnoc/my_oot/ip/<ip_name>/<ip_name>.xci
5. Created Makefile.inc in rfnoc/my_oot/ip/<ip_name> and added the following (replacing <ip_name> with the name of my IP:

   THIS_IP_DIR := $(dir $(abspath $(lastword $(MAKEFILE_LIST))))
   
   <ip_name>_NAME = <ip_name>
   LIB_IP_<ip_name>_SRCS = $(IP_BUILD_DIR)/$(<ip_name>_NAME)/$(<ip_name>_NAME).xci
   
   LIB_IP_<ip_name>_OUTS = $(addprefix $(IP_BUILD_DIR)/$(<ip_name>_NAME)/, \
   $(<ip_name>_NAME).xci.out \
   synth/$(<ip_name>_NAME).vhd \
   )
   
   .INTERMEDIATE: LIB_IP_<ip_name>_TRGT
   $(LIB_IP_<ip_name>_SRCS) $(LIB_IP_<ip_name>_OUTS): LIB_IP_<ip_name>_TRGT
       @:
   
   # This include provides BUILD_VIVADO_IP
   include $(TOOLS_DIR)/make/viv_ip_builder.mak
   
   LIB_IP_<ip_name>_TRGT: $(THIS_IP_DIR)/$(<ip_name>_NAME).xci
   $(call BUILD_VIVADO_IP,$(<ip_name>_NAME),$(ARCH),$(PART_ID),$(THIS_IP_DIR)/..,$(IP_BUILD_DIR),0)

6. Add the following to fpga/<oot_name>/CMakeLists.txt:

   install(
       DIRECTORY ip/
       DESTINATION ${GATEWARE_PKG_DATA_DIR}/ip
       COMPONENT gateware
    )

7. Add the following in the rfnoc block yaml file (rfnoc/blocks/<block_name>.yml)

   fpga_includes:
     - include: "fpga/<oot_name>/rfnoc_block_<block_name>/Makefile.srcs"
       make_var: "$(RFNOC_BLOCK_<block_name>_SRCS)"
     - include: "fpga/<oot_name>/ip/<ip_name>/Makefile.inc"
       make_var: "$(LIB_IP_<ip_name>_SRCS)"

8. Copied x310_rfnoc_image_core.yml from the gain example into the icores dir and replaced gain with the name of my block
9. Added RFNOC_REGISTER_IMAGE_CORE(SRC x310_rfnoc_image_core.yml) to icores/CMakeLists.txt
10. Installed the rfnoc block
11. Ran the following commands to build the image:

    mkdir icore_build && cd icore_build
    rfnoc_image_builder -y ../icores/x310_rfnoc_image_core.yml -F /uhd/fpga -B . -E ./ip --save-project -j $(nproc) -p /tools/Xilinx/Vivado -I ../

12. Got the error

Additional Information

Just a thought, but sometimes this happens if a build gets killed or has an error in which the IP starts getting generated but isn't fully generated. Can you look in the build location, in the build-ip directory, and try deleting the directory for the axi_intercon_2x64_128_bd IP, then rebuild the FPGA? It should regenerate that directory with a fresh copy of the IP automatically. Also, look in the logs/console to see if there are any errors at the point where it generates axi_intercon_2x64_128_bd that might give a clue. I can't tell if the IP is missing for you or if it just can't find it for some reason.

That didn't work. Got the same error.

Looking at the main build log file just gives me the same error.

Looking at the log file for axi_intercon_2x64_128_bd doesn't have any errors at all and seems to generate the files just fine. Although it doesn't generate an xci file and instead just creates a wrapper for the bd file. Not sure if it is also supposed to package it as an IP or not...
