AD7606X-FMCZ HDL project
===============================================================================
Overview
-------------------------------------------------------------------------------
The :adi:`AD7606` is a 8-/6-/4-Channel DAS with 16-Bit, Bipolar Input,
Simultaneous Sampling ADC. Each part contains analog input clamp protection, a
second-order antialiasing filter, a track-and-hold amplifier, a 16-bit charge
redistribution successive approximation analog-to-digital converter (ADC), a
flexible digital filter, a 2.5 V reference and reference buffer, and high speed
serial and parallel interfaces. The :adi:`AD7606` operate from a single 5 V
supply and can accommodate ±10 V and ±5 V true bipolar input signals while
sampling at throughput rates up to 200 kSPS for all channels. The input clamp
protection circuitry can tolerate voltages up to ±16.5 V. The AD7606 has 1 MΩ
analog input impedance regardless of sampling frequency. The single supply
operation, on-chip filtering, and high input impedance eliminate the need for
driver op amps and external bipolar supplies.
The :adi:`AD7606C` is a directly pin replacement (software and hardware) for
both AD7608 and AD7609, with higher input impedance, throughput rate and
extended temperature range with additional features such as 16/18-bit sample
size, system gain/offset/phase calibration, sensor disconnect detection,
lower Vdrive operation, diagnostics, additional oversampling ratios and per
channel analog input range selection with bipolar differential, bipolar
single-ended and unipolar single-ended options.
The :adi:`EVAL-AD7606B-FMCZ <EVAL-AD7606B-FMCZ>` and
:adi:`EVAL-AD7606C-18 <EVAL-AD7606C-18>` evaluation boards are designed to
help users to easily evaluate the features of :adi:`AD7606B`,
:adi:`AD7606C-16` and :adi:`AD7606C-18` analog-to-digital converters (ADCs).

Block design
-------------------------------------------------------------------------------
The data path of the HDL design is simple as follows:
- the parallel interface is controlled by the
:dokuwiki:`axi_ad7606x <resources/fpga/docs/axi_ad7606x>` IP core
- the serial interface is controlled by the :ref:`SPI_Engine <spi_engine>`
Framework
- data is written into memory by a DMA (:ref:`axi_dmac core <axi_dmac>`)
- all the control pins of the device are driven by GPIOs

Configuration modes
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The INTF configuration parameter defines the interface type (Serial or Parallel).
By default it is set to 0. Depending on the required interface mode, some
hardware modifications need to be done on the board and/or ``make`` command:
In case of the **PARALLEL** interface:
.. code-block::
make INTF=0
In case of the **SERIAL** interface:
.. code-block::
make INTF=1
.. note::
This switch is a **hardware** switch. Please rebuild the design if the
variable has been changed.
- JP5 - Position A - Serial interface
- JP5 - Position B - Parallel interface
The DEV_CONFIG configuration parameter defines the device which will be used:
- Options: 0 - AD7606B, 1 - AD7606C-16, 2 - AD7606C-18.
By default it is set to 0.
The NUM_OF_SDI configuration parameter defines the number of SDI lines used:
- Options: 1, 2, 4, 8.
By default is set to 8.
The EXT_CLK configuration parameter defines the external clock option for
the ADC clock:
- Options: 0 - No, 1 - Yes.
By default is set to 0.

Building the HDL project
-------------------------------------------------------------------------------
The design is built upon ADI's generic HDL reference design framework.
ADI does not distribute the bit/elf files of these projects so they
must be built from the sources available :git-hdl:`here <main:/>`. To get
the source you must
`clone <https://git-scm.com/book/en/v2/Git-Basics-Getting-a-Git-Repository>`__
the HDL repository, and then build the project as follows:.
**Linux/Cygwin/WSL**
.. code-block::
:linenos:
user@analog:~$ cd hdl/projects/ad7606x_fmc/zed
user@analog:~/hdl/projects/ad7606x_fmc/zed$ make DEV_CONFIG=2 INTF=0
The result of the build, if parameters were used, will be in a folder named
by the configuration used:
if the following command was run
``make DEV_CONFIG=2 INTF=0``
then the folder name will be:
``DEVCONFIG2_INTF0``
A more comprehensive build guide can be found in the :ref:`build_hdl` user guide.
Connections and hardware changes
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.. warning::
**The following hardware changes are required:**
Depending on the required interface mode, some hardware modifications need to
be done.
- **JP5** - A - Serial interface
- **JP5** - B - Parallel interface
- **JP7, JP12, JP13, JP14** - B - Differential operation
