The frontend synchronization upon time change was removed, but is
required to synchronize the RX frontend modules when sharing LOs on
TwinRX. This change restores the behavior.

Adds a BUILD_BASE_DIR makefile variable that allows you to specify the
base directory for FPGA build outputs. This allows you to put the
output from each run of make into a unique directory, or to run
multiple instances of make in parallel with each build's output being
put in a different directory. For example:
make X310_XG BUILD_BASE_DIR=/path/to/builds
Original-commit: bc6db8409ba756bbad0d0c158ffb00c614b58fd9
Adds a BUILD_SEED make variable that can be set to a 32-bit integer,
and adds an FPGA read-only register initialized by this variable.
Changing this variable will randomly affect the FPGA build results.
This can be useful when your build fails timing by a small amount,
allowing you to build again and get different results with the same
code.
For example, you could run the following to produce an FPGA build with
different timing results from the default build:
make X310_XG BUILD_SEED=123

Patch AR76780 was already listed as a requirement for X4xx and N3xx,
but was not listed as a requirement for X3xx and E3xx. This change
makes it required for all Vivado-based USRPs.
Original-commit: 5aa6bc4418a30d6e6fde80b80632f9f9115ea5c4
This adds the ability to do IP generation and FPGA builds using the
--jobs (-j) option with Make. For example, rather than generating each
IP one after another, you can generate up to N at a time using N Vivado
instances. This greatly reduces the IP generation time. Similarly,
parallel jobs can be used to easily build different FPGA variants
simultaneously.
Because FPGA builds can consume a lot of memory, care must be taken to
ensure that the number of jobs is not too high for the amount of memory
available.
New IP make targets were added for each USRP so that IP can be built
separately from the FPGA. The IP targets are now a dependency on each
FPGA target.
For example, you can generate the IP for X310 using 4 parallel jobs
using the following command:
make -j4 X310_IP
Or, build two X310 bitstreams simultaneously:
make -j2 X310_XG X310_HG

This causes the latest RFNoC protocol version to be used by default
and avoids the need to update YAML files every time the RFNoC
protocol version gets bumped.
Original-commit: 92016a585a5223a9a7678134e318e412875b64c2
Update USRP RFNoC iamge core YAML files to use the more consistent
device port names. Clean up the formatting and make the files more
consistent.
Original-commit: 6318eaeff548f760056af7c8172937a296409d25
This updates all RFNoC devices so that they get the RFNoC protocol
version and CHDR width in the same way, from the output generated by
the RFNoC image builder.

Change name in DRAM IP Makefile from IP_MIG_7SERIES_TG_SRCS to
IP_DDR3_16BIT_TG_SRCS to match the naming of other variables.
Original-commit: febf339e0df412e54cf43a204c280128d8ca1ec3
This adds DRAM support to E31x devices. Due to the size of the DDR3
memory controller, it is not enabled by default. You can include the
memory controller IP in the build by adding the DRAM environment
variable to your build. For example:
DRAM=1 make E310_SG3

This sets the ARCH and PART_ID environment variables so that the
selected part family is used for simulations by default. This can be
overridden by changing them in the Makefile for the testbench if a
testbench requires a specific part family. Prior to this change, the
default was always ARCH=kintex7, PART_ID=xc7k410t/ffg900/-2, which
required support for that part to be installed.
Original-commit: c176046dff4941bcec27b0b72e5a68264c4808e5
Update rfnoc_image_core.v to take into account the new image_core_name
fields and version strings. Add new rfnoc_image_core.vh. Update YAML
where needed.
Original-commit: b0033158a4c520063540881451d8daac91e98714
Change version from a numeric to a string, in order to
differentiate between versions like "1.1" and "1.10".
Original-commit: ca21048bd2f832b20bb36763f76d46b861b697a5
This renames e31x_rfnoc_image_core.* to e310_rfnoc_image_core.*. This
makes the naming consistent with the rest of the build process (which
uses "e310" for all variants of e31x) and fixes an issue in which the
wrong file name was used by rfnoc_image_builder.
Original-commit: bbd43b16e18ef0a0311ddf4635cbd29c4ac3c367
Fixing an issue in which a very slow radio_clk (due to low sample clock
rate) could cause bus transactions to be issued to the timekeeper
faster than it could service them, resulting in a timeout. This change
replaces RegPort with CtrlPort so that proper flow control can be
maintained to the timekeeper.
Original-commit: 2e910c5307702c3f3efb6dc8cb60f4f71ce11e67
Device was set to e31x, but this is not a valid device type. All e31x
devices use the e310 device type.
Original-commit: 60b76ebb31f9d1672c1b18367346b3fb522e13e9
This updates the makefiles for the testbenches so they can be run using
"make modelsim" without any additional hacks. The "xsim" and "vsim"
simulation targets also still work.
Original-commit: e962cc4a5e51e2326eb656ee2a779ea26774687b
- Fixed some incorrect comments
- Fixed some missing wire declarations for internal NIC
- Fix wire declarations for GPIO (they were declared too late)
Original-commit: b18eaa75de2d1dcba2a1be0ee0b862a57e976cca
Xilinx changed the way [all_registers -edge_triggered] is treated such
that set_max_delay constraints that use it can cause segmentation and
cause clocks to not be propagated to all endpoints. Changing to
[all_ffs] avoids this potential issue.

The FPGA codebase was removed from the UHD repository in 2014 to reduce
the size of the repository. However, over the last half-decade, the
split between the repositories has proven more burdensome than it has
been helpful. By merging the FPGA code back, it will be possible to
create atomic commits that touch both FPGA and UHD codebases. Continuous
integration testing is also simplified by merging the repositories,
because it was previously difficult to automatically derive the correct
UHD branch when testing a feature branch on the FPGA repository.
This commit also updates the license files and paths therein.
We are therefore merging the repositories again. Future development for
FPGA code will happen in the same repository as the UHD host code and
MPM code.
== Original Codebase and Rebasing ==
The original FPGA repository will be hosted for the foreseeable future
at its original local location: https://github.com/EttusResearch/fpga/
It can be used for bisecting, reference, and a more detailed history.
The final commit from said repository to be merged here is
05003794e2da61cabf64dd278c45685a7abad7ec. This commit is tagged as
v4.0.0.0-pre-uhd-merge.
If you have changes in the FPGA repository that you want to rebase onto
the UHD repository, simply run the following commands:
- Create a directory to store patches (this should be an empty
directory):
mkdir ~/patches
- Now make sure that your FPGA codebase is based on the same state as
the code that was merged:
cd src/fpga # Or wherever your FPGA code is stored
git rebase v4.0.0.0-pre-uhd-merge
Note: The rebase command may look slightly different depending on what
exactly you're trying to rebase.
- Create a patch set for your changes versus v4.0.0.0-pre-uhd-merge:
git format-patch v4.0.0.0-pre-uhd-merge -o ~/patches
Note: Make sure that only patches are stored in your output directory.
It should otherwise be empty. Make sure that you picked the correct
range of commits, and only commits you wanted to rebase were exported
as patch files.
- Go to the UHD repository and apply the patches:
cd src/uhd # Or wherever your UHD repository is stored
git am --directory fpga ~/patches/*
rm -rf ~/patches # This is for cleanup
