Due to the interface differences between HPS's AXI4 and DMA's AXI4, the
tool will try to automaticaly add some bridges between the two
interface. Unfortunatly it does generate timing issues at the f2sdram0
interface of the HPS instance. By explicitly instantiating an AXI
bridge, these timing issues disappears.
The reconfiguration interface for the Stratix10 XCVR has a different
address width. Prepare the register map layout of the project to support
this new architecture.
If we have a lot of peripherals connected to the CPU's memory interface,
the generated interconnect can grow to much decreasing the timing
margin.
One solution is to group the peripherals by its interface types and
functions and use bridges to connect them to the memory interface.
This commit adds the possibility to insert an Avalon Memory Mapped
bridge when we create the connection between the peripheral and CPU.
Should be used just with Avalaon Memory Mapped interfaces.
The ADRV9002 uses in the digital interface 1.8V, however the Zed VADJ is
selectable by a jumper can go up to 3.3V . Voltage levels higher than 1.8V
are detected by the EVAL-ADRV9002 board, asserting the VADJ_ERR pin.
If VADJ error is set high keep all drivers in high-z state and signalize
it to the software layer through a gpio line.
All input and output delays should be referenced to a virtual clock.
If the input and output delays reference base clocks or PLL clocks rather than
virtual clocks, the intra- and inter-clock transfer clock uncertainties,
determined by derive_clock_uncertainty, are incorrectly applied to the I/O ports.
See mnl_timequest_cookbook.pdf for more info.
By defualt the supported tool chain is Quartus PRO. If you want to
build the project with Quartus Standard, you need to define an environment
variable called QUARTUS_PRO_ISUSED with the value 0. (e.g. export
QUARTUS_PRO_ISUSED=0 )
Note: Not all projects going to build on Quartus Standard, you should
fix the errors if there is any.
There is a major compatibility issue between 2019.1 and 2019.2.
The file system_top.hdf got a different file extention. This will
cause a compilation failer in the end of the build. To save time
and fail earlier, upgrade the version mismatch message to ERROR.
If user still wants to build a branch with different tool version
the variable ADI_IGNORE_VERSION_CHECK should be set to 1.
On the Xilinx PHY the available PLL options depends on the lane rate.
Encoding is:
0 - CPLL
1 - QPLL0
2 - QPLL1
Since the selection of line rate is available from the project also the
PLL selection must be exposed.
The AFE's I2C interface should be pin-multiplexed to the FPGA. Also, add
a bidirectional IO buffer for the interface, and make sure it has weak
pull-up resistors.
Use over-writable parameters from the environment.
e.g.
make JESD_MODE=64B66B RX_RATE=24.75 TX_RATE=12.375 REF_CLK_RATE=375 RX_JESD_L=4 TX_JESD_L=4
make JESD_MODE=64B66B RX_RATE=16.22016 TX_RATE=16.22016 REF_CLK_RATE=245.76 RX_JESD_M=8 RX_JESD_L=2 TX_JESD_M=16 TX_JESD_L=4
make JESD_MODE=8B10B RX_JESD_L=4 RX_JESD_M=8 TX_JESD_L=4 TX_JESD_M=8
The previous mechanism was "probing" the DMAs for valid data. Better said,
each interpolation channel enabled it's DMA until a valid data was received,
then it disabled the DMA read and waited for the adjacent channel(DMA) to
receive a valid data. Only when for both channels had valid data on the
DMAs interfaces was the transmission started. This added an undesired and
redundant complexity to the interpolation channels. Furthermore, for continuous
transmission, using the above mechanism lead to a fixed phase(sample)
shift between the two channels at each start.
By using the streaming mechanism the interface is simplified and the
above problems are solved.
Because fmcomms2 was not supported on a Intel carriers the
fmcomms2_qsys.tcl file got outdated.
The arradio project has the same hdl design. Hence the update is
merely a copy of the arradio_qsys.tcl with small changes.
This commit fixes the critical warning regarding the missing clock
definitions.
- Defined MDC(MDIO) clocks
- Set false path on(to) the ps8 MDIO input pins. There are synchronization
stages in the GMII to RGMII converter for the CDC between the 375M refclk
and 2.5M MDC clock domains.
implemented mux for temp reading either from internal or external
source; updated regmap; added param to identify source for temp
information; updated tacho measurements; added AVG_POW param used
for tacho measuremet average useful for simulations; defaults for
tacho measurements changed to params and added registers; added
prescaler for fsm control, FSM updated; changed register write
process; connected INTERNAL_SYSMONE to regmap, value can now be
read by software;
Because of the rmii mode requirements(external 50MHz clock) the
board will have the rx_err signal replaced on the FMC connector with the
50MHz external clock (D08/D20).
The rx_er will be shifted to the D9/D21 pins.
The IO location of the laser_driver_otw_n was moved from FMC_HPC_LA27_N
to FMC_HPC_LA31 (laser_gpio[12]).
laser_gpio[11:0] assignments were shifted with one bit to MSB, and laser_gpio[0]
got the old location of the laser_driver_otw_n.
When channels are not swapped in groups of four but are completely out of order
the common control channel can't be reordered based on the index of the
channel.
The DDR controller for C2 for is much closer to the transceivers which
connect to the FMCp connector so designs does not have to span over all
three SLRs just over two reducing implementation and timing closure effort.
The second ADC was removed from the project, as the EV-AD7768-1FMCZ evaluation
board contains only one ADC. Therefore, all the IPs related to the
second ADC have been removed, too.
The data width supported by the spi IPs has been changed from 8 bits to
32 bits, therefore the axis_upscaler(util_axis_upscale_v1_0) and the
m_axis_samples_24(AXI4-Stream Data Width Converter) are no more necessary,
so they have been removed from the design.
The 24 bits width data transfer between the s_axis of axi_ad77681_dma
(AXI DMA Controller) and the offload_sdi of the spi_engine_offload is now made
directly.
Add commands to generate one extra file with resource utilization, in CSV format.
New commands executes only if ADI_GENERATE_UTILIZATION env variable is set.
