Hi Maria, Which IP are you trying to include? And is it failing when trying to simulate or only when building the FPGA? Some IP are easier to include than others. From your examples, it looked like you were trying to include the clock wizard. For that IP I usually just copy the MMCM or PLL code that Vivado generates rather than including the XCI, since the generated code is mostly just a single primitive, but I think referencing the XCI should also work.
So this is not the only way to do it, but the example we have for how to include IP in an OOT block is here: https://github.com/EttusResearch/uhd/tree/master/host/examples/rfnoc-example/fpga/ip/cmplx_mul To use this IP example, you need to include these lines in your OOT block's makefile (which is used for simulation): https://github.com/EttusResearch/uhd/blob/5333d3d12ffc21229ec4203a9ea1c7f68d82e57f/host/examples/rfnoc-example/fpga/rfnoc_block_gain/Makefile#L28 https://github.com/EttusResearch/uhd/blob/5333d3d12ffc21229ec4203a9ea1c7f68d82e57f/host/examples/rfnoc-example/fpga/rfnoc_block_gain/Makefile#L29 And add it to the Makefile.srcs for your block: https://github.com/EttusResearch/uhd/blob/5333d3d12ffc21229ec4203a9ea1c7f68d82e57f/host/examples/rfnoc-example/fpga/Makefile.srcs#L15 https://github.com/EttusResearch/uhd/blob/5333d3d12ffc21229ec4203a9ea1c7f68d82e57f/host/examples/rfnoc-example/fpga/Makefile.srcs#L16 Note also how it gets added to LIB_IP_XCI_SRCS. This is already include in the examles FPGA (X310): https://github.com/EttusResearch/uhd/blob/5333d3d12ffc21229ec4203a9ea1c7f68d82e57f/fpga/usrp3/top/x300/Makefile.x300.inc#L109 Make sure that line exists for the FPGA you are trying to build. But it looked like you were building an x300 variant, so it should be there. Wade On Mon, Jun 6, 2022 at 3:21 AM sp h <stackprogra...@gmail.com> wrote: > Ok, I'll take a look.
