      support rfsoc4x2 board · 643a0f8a
      Mitch Burnett authored
      Tested associated platform, rfdc, and onehundred gbe tutorial all working well
      The rfsoc4x2 port here uses the new vivado block design toolflow feature to
      build a block design instead of sosurcing an exported tcl script. The intention
      (hope) being that this is more forward and backward compatible with vivado
      versions. The rfsoc4x2 platform file here is rather messy now but demonstrates
      using the yellow blocks that are based in vivado block designs (mpsoc, xilinx
      axi interconnect, protocol converter) to place and wire those connections up.

      First pass working version using vivado block design · f722fa7d
      Mitch Burnett authored
      Here, the creation of a vivado block design inserts itself as a
      `create_bd` stage. This is done during the `add_compile_cmds` of the backend
      with each yellow block implementing a `modify_bd` method.
      Considering that the generation of a block design is a list of tcl cmds it would
      be possible to have this functionality be contained within the `gen_tcl_cmds`.
      However, the idea here is to provide an infrastructure with the block design
      (.bd) file treated more as a source like the top module being a Verilog class.
      To do keep this in `gen_tcl_cmds` as it is implemented now would require a
      modification to that structure, or to have the block design more amorphous to
      the process.
      However, considering this, and that the rfdc still uses `gen_tcl_cmds` that is
      accomodated here by waiting until all yellow blocks have a chance to modify
      block design and using the save/validate as part of a pre-synth stage. The idea
      is to migrate the rfdc to use a `modify_bd` unless otherwise reverting back to
      `gen_tcl_cmds` for everything.

      working version for the rfsoc4x2, but breaks any other board · baace635
      Mitch Burnett authored
      there are still assumptions that need to be made regarding the connections and
      how to wire them up. This needs to be worked out next.
      Also the approach to adding a block design to the `VivadoBackend` class requires
      that it doesn't break the flow for designs that do not use a board design. This
      needs to be tested.

      change yaml loader from SafeLoader to Loader · cb0ac32e
      Mitch Burnett authored
      Loader (or UnsafeLoader) is the 'backwards compatability' option and at the
      moment SafeLoader should work, but something like castro.yaml might break
      something so downgrade and test first

      bug fixes in rfdc mask · 998739ca
      Mitch Burnett authored
        * fix gateway bitwidth and drawing update
        * fixes mixer/output configurations for both ADCs and DACs on both DT and QT.
      slices within a tile can propely be configured differently
        * system clocking is now hidden for DT parts where the DT platform file is
      used to pass along the clocking information like previously done (this needs to be
      updated and improved since 3rd gen DT parts can support clock forwarding)

      change to configure each tile, support dac · 5a6b64cc
      Mitch Burnett authored
        * The previous rfdc applied same adc slice configuration to all enabled tiles. Now can configure independently.
        * Add support for DAC and tested on 49dr parts. Needs to be abstracted to
        * generic rfsoc parts to work on DT and first gen parts
        * Still need to validate DAC output configurations
        * The mask does take a long time to load, working on ways to improve response
        * There is a bug with adc port configuration may not have the correct width,
          Disable slice, apply, re-open and re-enable slice
        * Change tile clocking to move it out of yaml and into a clocking tile tab.
          There is no real check on validation, vivado will fail for invalid clocking

      Merge branch 'm2019a' into rfsocs/merge-casper-astro/m2019a · de5e6e6f
      Mitch Burnett authored
      Bring rfsoc up to date with m2019a. Development was originally from `master` but
      using m2019/m2020 and as code added was isolated to developing the yb/hdl
      support needed for other blocks was not needed and affected.
      Notes on from about resolution to some of what were the conflicts shown below:
      with 100g, preference was given to keep the rfsoc development branch work as it
      incorporates on top what m2019a would have supported but now is more general by
      supporting zcu216/208 where gtys are split between quads.
      For the 40g commits, those were discrepancies in the diverging development of
      master and m2019 with preference to adopt all of m2019a

      Create VitisBackend moving experimental functionality from VivadoBackend · e35e543e
      Mitch Burnett authored
      Rework of previous commit to add the new VitisBackend class. The flow can
      be ran with --vitis switch along side the --backend command or standalone
      with a valid `.xsa` with the --xsa switch.

      experimental addition of full xsct/dt creation in toolflow · 25a4f96c
      Mitch Burnett authored
      This somewhat marks a milestone in supporting rfsoc/rfdc within the toolflow.
      Because with these changes here in addition with supporting software from
      casperfpga/tcpborphserver a design can be created from simulink and loaded with
      casperfpga and functionality of the rfdc and board can be done without any other
      manual bootstrapping.
      This current commit will break for non zynq soc's. It merley is an intermediate
      staging of complete and successful integration of the rfdc from platform, to yellow block,
      to the linux software driver. The hsi/xsct/py scripts that were added have been
      removed in favor of just tracking the required within the rfdc yellow block.
      This was a choice made to just keep the required dt generation within the rfdc.
      Because at this point, while any MPSoC with a board desgin can be used to create
      a valid Vitis platform and software project we are really only using it within
      the context of rfdc and rfsoc. However, the way it is implemented *does not*
      limit the ability to extend further. Instead, it just provides a convenient way
      to keep functionality where it needed most until (or maybe it never happens)
      when more of this functionality wants to be extended. At that point perhaps a
      more general implementation.
      From here is to start a small Vitis back end class that will allow compatability
      with all of the tools

      Update rfsoc platform support for dt generation with .xsa export w/ bitstream · 4e372ed5
      Mitch Burnett authored
      Also more formally support the pynq rfsoc2x2 by finishing out its platform
      definition, yellow block creatino and adding to the xps library
      zrf16_29dr base board design updated to use the correct ddr for the board. It
      had been working but noticed that the ddr was different than the original
      schematic which is what the board design was set for.

      intermediate updates to hsi/xsct scripts for rfdc dt · b4269c92
      Mitch Burnett authored
      most likely will remove these from the repo to implement
      within the yellow block. Until much more of the Vitis/software/device
      tree support is integrated it would make more sense for everything to
      be local to within the rfdc. When more functionality is added for xsct
      support it could be more advantages to have more scripts or structure

      support 100g on rfsoc platforms · 1a8aacf1
      Mitch Burnett authored
      Add support for zcu216/208/111 zrf 29/49dr
      Extends CMAC 100G IP sources to support instancing 2 COMMON primitives for GTYs
      split between 2 MGTs. This is needed for platforms like ZCU216/208 that use
      4xSFP28 but with 2 GTYs into bank 128 and the other 2 into bank 129. Out of the
      box, the Ethernet 100G Subsystem IP does not support this configuration, only
      supporting when all 4 lanes for CAUI-4 come into the same quad.
      Changes here modify how the CMAC IP is instanced to not include `GTYE4_CHANNEL`
      placement and shared resources like `GTYE4_COMMON` primitives within the core.
      Instead these are instanced with other modules that allow for dynamic changes
      based on platform layout to "unify" support across different platforms of the
      two possible GT placements. The `gmacqsfptop` modle now instances one of the
      `cmac_usplus_core_support` modules wrapping the CMAC IP to interface correctly
      with these new modules common to different
      These changes depend on the changes made in the `kutleng 100G IP` repo by
      modifying the `gmacqsfptop` module to now instance the correct support core and
      use the generic to allow for placing additional COMMONs. The kutleng repo is to
      be placed at `jasper_library/onehudred_gbe/`
      Both the RS-FEC and non-RS-FEC (wrapped by `cmac_usplus_core_support_norsfec`)
      version have been updated and was tested on a zcu21. Note, had to disable
      RS-FEC on the receving switch/NIC when testing the non-RS-FEC over CR4.
