The derived clocks of the zynqmp core are not calculated correctly due
rounding issues, instead of 100MHz the value of 99999001 is received
causing warnings during system validation.
This can be fixed/worked around with the proper reference clock
definition.
The 2020.1 Xilinx tools have a different tcl procedures to build the boot.bin
file.
This commit updates the adi_make tcl flow for the new tools. The new
process is not backwards compatible with tools older than 2020 version.
In order to workaround optimization issues hit in Vivado 2020.2,
set ADI_USE_OOC_SYTHESIS variable by default to 1. This will build
projects in Out Of Context mode.
Projects can be build in Project Mode by exporting ADI_USE_OOC_SYTHESIS=n.
Update vivado version to 2020.2:
- update default vivado version from 2020.1 to 2020.2
- add conditions to apply specific contraints only in Out Of Context mode.
- update DDR controler parameters for vcu118 and kcu105 dev boards
This commit removes two invalid ad_connect invocations, which weren't
caught in the original tests for commit cdda184007.

The goal of this commit is to make sure there isn't any significance to
the order in which parameters of ad_connect are specified.
As an example, previously you could only `ad_connect target VCC`, while
`ad_connect VCC target` would fail.
Note: This code intentionally ignores bd_{,intf_}ports, because
these can all be treated as bd_pins.

For fixing "Failed to reset the device and set SPI Config"
error, both clockPolarity and clockPhase should be disabled
or both enabled. By default both are unset.

This commit fixes the 16.5Gbps lane rate case where the link drops
after few seconds an initial successful link up happens.
A few seconds delayed calibration process can workaround this but with
having the differential drivers swing increased this is no longer
required.
This will allow building base test harnesses and place on top of them
existing block designs for simulation purposes.
Test harnesses will contain basic functionality like
- clock and reset generators
- AXI master to aid register access of the cores.
- memory model of the DDR
- interrupt controller
Existing procedures (ad_mem_hp0_interconnect, ad_cpu_interconnect, ... ) will
connect to this harness as they do to a real base design.
To support deterministic latency with non-power of two octets per frame
(F=3,6) the interface width towards the transport layer must be resized
to match integer multiple of frames.
e.g Input datapath width = 4; Output datpath width = 6;
for F=3 one beat contains 2 frames
for F=6 one beat contains 1 frame
The width change is realized with a gearbox.
Due the interface width change the single clock domain core is split
in two clock domains.
- Link clock : lane rate / 40 for input datapath width of 4 octets 8b10b
- lane rate / 20 for input datapath width of 8 octets 8b10b
- lane rate / 66 for input datapath width of 8 octets 64b66b
- Device clock : Link clock * input data path width / output datapath width
Interface to transport layer and SYSREF handling is moved to device clock domain.
The configuration interface reflects the dual clock domain.
If Input and Output datapath width matches, the gearbox is no longer
required, a single clock can be connected to both clocks.
In most of the standalone projects the generic project creation flow is not followed. The project's device
is defined manualy. This fix makes sure that those projects still builds without an issue.
NOTE: In these case we should use adi_project_create directly in system_project.tcl.
Without defining this signal, the UART lines receive garbage data
when no cable is connected to the J4 USB UART port.
The GPIO9 is enabled in the reference base design along with the
4MA CURRENT_STRENGTH constraint on the UART pins
When phase alignment is active, the PFD frequency value should be used
as outclk1 actual frequency.
The configuration interface of the fPLL does not support fractional values.
If the reference clock is fractional, the tool will throw an error that requirement
above is not respected.
Round up the reference clock for the SERDES and the lane rate in order to
overcome this issue, until it's not fixed by Intel.

-change the video memory interfacing from f2h_axi_slave to
f2h_sdram0
- add f2h_sdram1 port as the default interface for converter DMA
- set as default the full HD resolution at 60 FPS (pixel clock 148.5MHz)
- use a second 200MHz(198MHz) clock from the pixel_clk_pll, as DMA source
to destination clock.
Also modified the FIFO ports to have the same widths so that in a
future commit the bypass would be available for cases when the
sampling rate won't be the maximum rate or the number of channels
active will be less than maximum number of channels
Switch RX path reset to be controlled by the TPL and use
RX SYSREF as external synchronization for the ADC TPL
Use TX SYSREF for synchornizing the TX DDS
The device clocks are AC coupled LVDS lines without external termination.
For proper operation internal differential termination must be enabled,
the DQS_BIAS will DC bias the AC coupled signal to VCCO/2 (1.8/2) 0.9V
Added reference design for the ad9656 evaluation board coupled with the
zcu102 carrier board. The JESD204 communication link that transfers data
from the 4 ADCs to the FPGA has the following paramenters : L=4, M=4, S=1,
F=2, HD=0, N=16, NP=16. The JESD204 line rate is configured to be 2.5GHz.

Note, the current SCLK to spi_clk ratio is four. That means, the input
delay in the MISO line is 25% of the SCLK period.
If the SCLK to spi_clk ratio is changing, this constraint must be
updated.
Generate a higher frequency of spi_clk using an axi_clkgen. (MMCM)
CAUTION: ad7768-1 is still violating the standard SPI timing,
reducing the timing window significantly for the last bit (or last high
bit).
Ignore the following critical warning on DMAC instance:

cannot have value "old" when different read and write clocks are used.
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.
