(1) Synthesizable AxiLiteIf
(2) Simulation model for AxiLite contains an AxiLiteTransaction class
and an AxiLiteBfm class.
Important Methods
a. wr - performs non-blocking write and checks for expected response
b. wr_block - performs a blocking write and provides response
c. rd - performs a non-blocking read and checks for expected response
d. rd_block - persforms a blocking read and provides response
The model allows parallel execution of reads and writes, but enforces
rd and write ordering when using the above methods. When transactions
are posted directly, ordering is not guaranteed, and reads and writes
are put on the interface immediately.

Adds LATENCY parameter to control the ammount of pieplineing. Adds a
clock enable to control the advance of the pipeline.
Used in xport when calculating new UDP headers for CHDR traffic.

This fixes the rfnoc_null_src_sink, chdr_crossbar_nxn, and
chdr_stream_endpoint blocks so that wider CHDR widths are properly
supported. It also updates PkgChdrBfm to able to properly test these
blocks. The testbenches have been updated to test both 64 and 512-bit
widths.

The existing SPI core (simple_spi_slave.v) was limited to 32 bit. This
commit adds a second spi core with capability to transfer up to 64 bits
while keeping the same amount of resources when using generic setting
MAX_BITS = 32. Furthermore, the new module aligns mosi and miso with the
edges of sclk. The register stages were not aligned in the existing
version.

During recreation of block diagrams any RTL modules will be kept in
hidden directories within the build directory. Updates of the RTL
sources might not be taken into account. Solution is to remove Xilinx's
hidden project directories before calling vivado.

Previously, if a write occurred before the FIFO was ready then a
write could hang as the data channel would complete but leave the
address channel in a state where it would never complete. The fix is
to hold off acknowledging on the data channel until the FIFO is ready.
Original-commit: 3f6ad749b06094b0e16b412a791ba3f2ac509600
Add DEFAULT_M and DEFAULT_N parameters for rate changing cores.
This allows the host to not need to configure fixed rate change
cores.

This change allows detection of attempting to execute setupenv.sh
rather than sourcing it, which is required.

This adds support for colored output and support for directories added
to the list of source files (for HLS support).
Original-commit: 5b3d66e5b7cedb7098de3e4dbbee70af04a3626e
For HLS builds, the output file names aren't known in advance. This
makes it difficult to write the Makefile to pull in the files and pass
them to the build tools. This change allows you to add a directory as
your HDL source so that all files in the directory will be pulled in by
the build process.

The address ranges configured for the AXI interconnect IP limited the
amount of accessible DRAM to two 32 MB regions. This change makes the
full 1G available to all DRAM ports.
Original-commit: bba0cddfadcb744e8a6fae27d57ba8d3995eaf64
The decimation in the rx_frontend_gen3 was added to reduce the bandwidth
between the Radio and the DDC due to the limitation in bandwidth over
the crossbar for dynamically connected blocks. The default FPGA image
for the X300 now has a static connection between the Radio and DDC, so
this is no longer necessary.
This change allows the TwinRX receive channels to be time aligned with
channels from other daughterboards so they can be used in the same
streamer.

This updates the chdr_to_axis method so that it doesn't change the
input chdr_packet object. This is useful in case there are other
references to that object in use. Not modifying the object means that
you don't always have to copy the object before passing it to this
method.
Original-commit: 259506c4993834d9ef8ccb48635623552b075237
The axis_data_to_chdr block previously only sampled the sideband
information at the end of the packet. This adds a parameter that
controls if the sideband information should be sampled at the beginning
of the packet or the end of the packet. In the former case, large
internal packet buffers are not required.

Add -voptargs=+acc to the default options when running vsim. This
option enables debug command access to objects in the design, which is
generally needed for debugging in the GUI.

The axis_split module takes a single AXI-Stream input and duplicates it
onto multiple AXI-Stream outputs. This block correctly handles the
somewhat tricky flow-control logic so that the AXI-Stream handshake
protocol is honored at all top-level ports.

This commits enables the FPGA build infrastructure to require a very
specific Vivado version, all the way to the patch level.
Vivado typically has the following version format:
Year.release.update_patch
This commit enables setupenv_base.sh to optionally look for the
environment variable VIVADO_VER_FULL, which should contain the
full Vivado version in the format specified above.
Vivado is directly used to retrieve the installed version, returning
an error if the requested version is not found.
Example in setupenv.sh (which calls setupenv_base.sh):
VIVADO_VER=2019.1
VIVADO_VER_FULL=2019.1.1_AR73068
The setupenv.sh script will setup Vivado 2019.1, but it will also
verify that both Update 1 and patch AR73068 are installed.

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.
Original-commit: 55e422535292c29de00b80f15b0a49ca3fb94f26
viv_utils.tcl will now read files with the .sdc suffix using the
read_xdc Vivado command. This is especially useful when I/O timing
constraints in the FPGA and CPLD need to depend on a common constant.

The latency through the combiner is static if only one master interface
is used and PRIORITY=1 is set.

Xilinx changed the default Vivado install location from /opt/Xilix to
/tools/Xilinx. This commit adds support for finding Vivado in either
the new location or the old location.

This adds the "modelsim" simulator option to run_testbenches.py to allow
for regression testing of the native ModelSim simulation target.
Original-commit: 39d6007ca7e3b27e8230db6690faa7469ca62cb2
This adds a simulation make target that allows you to run ModelSim
natively rather than through Vivado.
Adds or modifies the following simulation make targets:
make vlint - Brake up compilation to Verilog/SystemVerilog/VHDL
make modelsim - Depends on make vlint and invokes modelsim
Adds the following variables:
MODELSIM_ARGS - Added to invocation of ModelSim
SVLOG_ARGS - Added to SystemVerilog invocation of vlog
VLOG_ARGS - Added to Verilog invocation of vlog
VHDL_ARGS - Added to VHDL invocation of vcom

When using viv_modify_tcl_bd, two Vivado instances are open:
1. GUI-mode Vivado that opens a TCL-based BD for the user to edit.
2. Batch-mode Vivado that saves changes from (1) and rewrites the TCL
source file.
During (2), the previous tool implementation was saving layout
information in the TCL source file. This layout info gets outdated
when the BD is reopened, because (1) regenerates the layout to provide
a clean BD diagram in the Vivado GUI.
Furthermore, each time the BD is open, the layout information will
vary due to Vivado's window size, thus creating untracked changes in
the source TCL file.
This commit removes the command option that requests Vivado to save
layout information.

For example, the ChdrPacket typedef is being renamed from ChdrPacket to
ChdrPacket_t. This allows the code to distinguish between the
unparameterized class and the already parameterized class. This isn't
strictly necessary, but it makes some Vivado 2019.1 bugs easier to work
around. It also makes the code slightly less ambiguous.
