+PulSAR ADC PMDZ
+================================================================================
+
+Overview
+-------------------------------------------------------------------------------
+
+The purpose of this testbench is to validate the serial interface functionality
+of the :git-hdl:`projects/pulsar_adc` reference design.
+
+The entire HDL documentation can be found here
+:external+hdl:ref:`PULSAR-ADC HDL project <pulsar_adc>`.
+
+Block design
+-------------------------------------------------------------------------------
+
+The testbench block design includes part of the PulSAR ADC HDL reference design,
+along with VIPs used for clocking, reset, PS and DDR simulations.

+
+Configuration parameters and modes
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The following parameters of this project that can be configured:
+
+-  CLK_MODE: defines clocking mode of the device's digital interface:
+   Options: 0 - SPI mode
+-  NUM_OF_SDI: defines the number of MOSI lines of the SPI interface:
+   Options: 1 - Interleaved mode
+-  CAPTURE_ZONE: defines the capture zone of the next sample.
+   There are two capture zones: 1 - from negative edge of the BUSY line
+   until the next CNV positive edge -20ns
+-  DDR_EN: defines the type of data transfer. In echo and master clock mode
+   the SDI lines can have Single or Double Data Rates.
+   Options: 0 - MISO runs on SDR.
+
+Build parameters
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The parameters mentioned above can be configured when starting the build, like in
+the following example:
+
+.. shell::
+   :showuser:
+
+   $make CLK_MODE=0 NUM_OF_SDI=1 CAPTURE_ZONE=1 DDR_EN=0
+
+but we recommend using the already tested build configuration modes, that can be
+found in the ``cfg`` section.
+
+Configuration files
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The following configuration file is available:
+
+   +-----------------------+-----------------------------------------------+

+CPU/Memory interconnect addresses

+
+Below are the CPU/Memory interconnect addresses used in this project:
+
+=========================  ===========
+Instance                   Address
+=========================  ===========

+
+
+Test stimulus
+-------------------------------------------------------------------------------
+
+The test program is structured into several tests as follows:
+
+Environment Bringup
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The steps of the environment bringup are:
+* Create the environment
+* Start the environment
+* Start the clocks
+* Assert the resets
+
+Sanity Test
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This test is used to check the communication with the AXI REGMAP module of the
+AD463X SPI Engine interface, by reading the core VERSION register, along with 
+writing and reading the SCRATCH register.
+
+FIFO SPI Test
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The FIFO SPI Test verifies the simple serial transfers, made through the
+Execution module.
+
+The steps of this test are:
+
+* Start the SPI clock generator (axi_clkgen)
+* Configure the conversion signal generator (axi_pwmgen)
+* Enable SPI Engine & configure the Execution module
+* Set up the interrupts
+* Generate a FIFO transaction
+* Capture and compare the results, using the PEEK register of the AXI SPI Engine
+
+Offload SPI Test
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The Offload SPI Test verifies the Offload module functionality.
+
+The steps of this test are:
+
+* Configure the DMA
+* Configure the Offload module
+* Start the Offload module
+* Capture and compare the Offload SDI data
+
+Building the test bench
+-------------------------------------------------------------------------------
+
+The testbench is built upon ADI's generic HDL reference design framework.
+ADI does not distribute compiled files of these projects so they must be built
+from the sources available :git-hdl:`here </>` and :git-testbenches:`here </>`,
+with the specified hierarchy described :ref:`build_tb set_up_tb_repo`.
+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**
+
+*Example 1*
+
+Build all the possible combinations of tests and configurations, using only the
+command line.
+
+.. shell::
+   :showuser:
+
+   $cd testbenches/project/pulsar_adc_pmdz
+   $make
+
+*Example 2*
+
+Build all the possible combinations of tests and configurations, using the
+Vivado GUI. This command will launch Vivado, will run the simulation and display
+the waveforms.
+
+.. shell::
+   :showuser:
+
+   $cd testbenches/project/pulsar_adc_pmdz
+   $make MODE=gui
+
+*Example 3*
+
+Build a particular combination of test and configuration, using the Vivado GUI.
+This command will launch Vivado, will run the simulation and display the
+waveforms.
+
+.. shell::
+   :showuser:
+
+   $cd testbenches/project/pulsar_adc_pmdz
+   $make MODE=gui CFG=cfg1 TST=test_program
+
+The built projects can be found in the ``runs`` folder, where each configuration
+specific build has it's own folder named after the configuration file's name.
+Example: if the following command was run for a single configuration in the
+clean folder (no runs folder available):
+
+``make CFG=cfg1``
+
+Then the subfolder under ``runs`` name will be:
+
+``cfg1``
