Reference design for AD4858 20-bit, low noise 8-channel, SAR ADC with
buffered differential, wide common range picoamp inputs.
The design supports:
- CMOS and LVDS interfaces(at build time)
- Runtime sampling changes
- Store captured samples in RAM, through DMA (available via software support)
Documentation at: https://wiki.analog.com/resources/eval/user-guides/ad4858_fmcz/ad4858_fmcz_hdl
The axi_ad4858 IP core is design as the HDL interface for the AD4858 ADC.
Features:
- AXI based configuration
- LVDS and CMOS support
- Configurable number of active data lines (CMOS - build-time configurable)
- Oversampling support
- Supports packet formats 0,1,2 or 3
- CRC check support
- Real-time data header access
- Channel based raw data access(0x0408)
- Xilinx devices compatible

The project controls the AD3552R digital-to-analog converter and transmits data written in the DDR memory to the QSPI interface of the DAC.
The reference clock is generated by an axi_clkgen IP and is configured to output a 133MHz signal.
If both channels are enabled and data streaming is DDR the sample rate is 16.65MSPS.
If just one channel is enabled and data streaming is DDR the sample rate is 33.3MSPS.
The VADJ voltage should be set to 1.8V.

The custom interface IP for AD3552R DAC has more operation capabilities:
- 8b register read/write SDR/DDR
- 16b register read/write SDR/DDR
- data stream SDR/DDR ( clk_in/8 or clk_in/4 update rate)
- selectable input source : DMA/ADC/TEST_RAMP
- data out clock(SCLK) has clk_in/8 frequency when the converter is configured and clk_in/2 when the converter is in stream mode
- the IP reference clock (clk_in) can have a maximum frequency of 132MHz
- the IP has multiple device synchronization capability when the DMA is set as an input data source

-Updated description of some fields of these registers: REG_CHAN_CNTRL_1,
REG_CHAN_CNTRL_2, REG_CHAN_CNTRL_3, REG_CHAN_CNTRL_4, REG_USR_CNTRL_4,
and REG_USR_CNTRL_5
-Added two new registers, both with their own fields and description:
REG_CHAN_CNTRL_9 and REG_CHAN_CNTRL_10

The DDS for each channel was synchronized by the main channel.
One problem with this aporoach is that when a user sets a DDS that
is not from the main channel the sinchronization does not happend.
This behavior is not user friendly in IIO-Oscilloscope or within other
configuration methods.
This commit keeps all channels in sync by triggering the sync on all
channels from each individual channel.
Signals/buses declared in the docs that does not exist in the
components.xml files will raise a warning.

Add documentation info to the README.md
At adi_hdl_parser.py, filter "_signal_clock" and "_signal_reset"
pseudo buses from component.xml files, append them as description
in the ports table, in the format
"{Bus} [...] is synchronous to this {domain}".
Also, adds collapsible directive

Automate table generation for register maps.
Based on tfcollins' vger python scripts.
There are docs/adi_regmap_*.txt with more than one regmap per file,
so the logic changed to allow that.
Using title tool as the unique identifier now.
It has a global option to set the default state (hidden or visible)
for the collpasible tables.
Also remove CSVs.

The parameters directive allows to almost automatically generate the
parameters table.
It allows to add rich descriptions to the parameters, such as references,
while checking if they exist in the *_hw.tcl file a obtaining the types
and default values.
However, it cannot obtain parameters generated from a foreach loop yet,
making it incompatible with the axi_dmac_hw.tcl file for example.
This commit also joins the other extensions into a single adi_links
extension.

Add support for DDS phase width greather than 16.
The software should read the DDS phase data width register and configure
the DDS init and increment registers accordingly, otherwise the obtained
DDS output frequency will not be the desired one for DDS phase width
different than 16.
DDS_incr = (f_out * 2^(phase_width) * clkratio)/f_if

The generic project dependency list contains:
system_top*.v
system_bd.tcl
system_project.tcl
system_constr.xdc
This items will not be included in the auto generated makefiles. But
used as generic dependency.
This commit adds:
-wildcard check of system_constr*.xdc.
-wildcard check of system_constr*.tcl.
Add files CODEOWNERS, filled with owners per each hdl project and some IPs.
Specific code owners will be automatically added as reviewers, whenever new
PRs are opened, depending on affected folders/files from repo.
CODEOWNERS file can be different on each branch.
PULL_REQUEST_TEMPLATE.md content will populate all new PR description field.
Beside PR description, it contains a list of checkboxes, ensuring all
team members follow the same guidelines and enforce best practices.
PR Template applies for PRs against repository's default branch.
Both files were added in .github
