Any packet less than CUT_THROUGH bytes has a high chance of getting
stuck in the TX FIFO of the xge_mac_wrapper. In cut-through mode we
were waiting for CUT_THROUGH bytes before transmitting the packet.
|
|
|
|
|
|
|
| |
When operating in cut-through mode the hold off from the MAC was not
applying back pressure, so when the TX interface filled up, data was
dropped. This bug was introduced when cut-through was added, and does
not impact the original implementation.

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.

The DMA FIFO is needed for DDR3 BIST, so it is being restored for now.

Add the Replay RFNoC block to the RFNoC core image for x300, x310, n300,
n310, n320/n321, and e320. The Replay block is contained within its own
static connection, so previous default behavior is still supported.

This updates the IO signatures so that all devices and RFNoC blocks use
the same IO signature for the DRAM. This is needed because the IO
signatures must match between the RFNoC blocks and the devices. This
means that some devices have extra bits in the IO signature for the
address, but the extra bits will simply be ignored.

- Adds test coverage for stream command and status packets
- Cleans up report output during simulation
- Stops clocks at the end of simulation, so chdr_stream_endpoint_tb can
be run directly instead of just chdr_stream_endpoint_all_tb

This updates PkgChdrBfm to correct some errors when modeling stream
command and stream status packets.
- Fix behavior when CHDR_W = 512
- Fix assertions in read_ctrl()

This change allows the entire 2 GiB address space to be accessed on
each memory port.

This changes the behavior of the stream command with the INIT OpCode
such that sending the command with 0 for the values causes no flow
control stream status packets to be sent in response to incoming data.

This implements the same change that was made for E31x. The same issue
wasn't reproduced on N3xx, however this change keeps the code
consistent and eliminates the potential for the same problem.

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.

Add some missing CtrlPort signal widths to ctrlport.vh.

It was set to E320_HG, which is not a valid target, causing build errors
unless -t E320_1G was provided to rfnoc_image_builder.

Device was set to e31x, but this is not a valid device type. All e31x
devices use the e310 device type.

This change prevents packets from being chopped midway if the
switchboard configuration is changed when a packet is in flight.

Thange allows the mux to switch cleanly between packets, if the mux
select input is changed while a packet is in flight.

The clock crossing of the ctrlport used FIFOs to transfer requests and responses
between clock domains. This commit adds a handshake based on the pulse
synchronizer to reduce the resource usage for ctrlport clock domain crossing.
Data is stored in a single register while the pulse synchronizer handles the
signaling of valid flags.

This fixes some incorrectly handled clock crossings from axis_data_clk
to axis_chdr_clk, which could have manifested as timing failures (on
E320) or incorrect behavior, depending on the product and noc_shell
configuration.
Also cleans up trailing white space.

The max FFT size was 4096, but we don't currently have any devices that
can do that without modification. This is because, currently, the FFT
size must be the same as the packet size, and the largest packet
size supported by most devices is about 8000 bytes, or 2000
sc16 samples. Therefore, the largest FFT size supported without
modifying other code is 1024 samples.
This change frees up about 21% of the LUTs and 36% of the BRAM used by
axi_fft and makes the software block controller and the IP agree on the
maximum FFT size.
|
|
|
|
|
| |
This adds additional tests to the testbench to cover register reads and
basic IFFT functionaltiy.

This commit derives parameters for MAX10 devices if provided by the
DEVICE parameter.
MAX10 devices FIFO generator support up to 36 bit wide FIFOs using
embedded memory (M9K) in simple dual port mode, which is treated
equally to RAM in the parameters.
In combination with sorting the ctrlport signals by usage, the used
resources can be reduced on the MAX10 devices from 6 to 3 M9K blocks
for a ctrlport_clk_cross instance without time and portids.

- Detect dropped words at the dispatch level. This prevents
an overflow on CHDR from block CPU.
- Dropped packets are recorded as CPU or CHDR drop count
- Refactor to put chdr_xport_adapter.sv in different clock
domain to improve timing
- Unwrinkle tkeep/trailing transitions

This change fixes the case where CHDR_W < ITEM_W*NIPC.
It also adds a state machine to stall the input to the pyld_fifo to
ensure that the pkt_info_fifo will not overflow. Previously in some
cases it allowed the same word to be inserted into the pyld_fifo
multiple times.

This adds new image files which come with a DRAM FIFO. The addition of
an N320 image with a DRAM FIFO allows DDR3 BIST to be run on an
assembled (motherboard + daughterboard) N320.
This image is intentionally very similar to the N300_AA and N310_AA
targets which serve the same purpose of providing an image with a DRAM
FIFO for their respective devices.

- Made some things optional to reduce logic when
used with the new xport_sv:
(1) Clocking to sys_clk
(2) Preamble insertion
- New options to CUTTHROUGH faster on the TX path.
The new xport_sv already has a gate to accumulate at
its clock crossing.

This module takes an AXI-Stream without TLAST and outputs the
same AXI-Stream with TLAST based on the provided packet size
input.
