ZC706 Quick Start Guide

All the products described on this page include ESD (electrostatic discharge) sensitive devices. Electrostatic charges as high as 4000V readily accumulate on the human body or test equipment and can discharge without detection. Although the boards feature ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. This includes removing static charge on external equipment, cables, or antennas before connecting to the device.

This guide provides quick instructions on how to setup the EVAL-AD7616SDZ on:

• ZC706 using the SPD-I-FMC adapter

Using no-OS as software

Necessary files

The following files are needed:

• HDL boot file: system_top.xsa

• no-OS project: projects/ad7616-sdz

Instructions on how to build the HDL boot file from source can be found here:

• AD7616-SDZ HDL project build documentation. More HDL build details at Build an HDL project.

Required software

• AMD Xilinx Vivado and Vitis (downloading Vitis from here will include Vivado as well)

• A UART terminal (Putty/Tera Term/Minicom, etc.) with baud rate 115200 (8N1)

Required hardware

• ZC706 FPGA board and its power supply (12 V DC)

• EVAL-AD7616SDZ evaluation board and a 7 V to 9 V DC power supply (J7)

• SDP-I-FMC adapter board

• 2 x Micro-USB cable (UART & JTAG)

More details as to why you need these, can be found at Prerequisites.

Testing

Creating the setup

Follow the steps in this order, to avoid damaging the components:

1. Connect the EVAL-AD7616SDZ to the SPD-I-FMC adapter

2. Plug the SPD-I-FMC into the FMC connector of the ZC706

3. Set the VADJ voltage on the ZC706 to 3.3 V

   Warning

   Because of the SPD-I-FMC, the VADJ level on the ZC706 must be set to 3.3 V.

4. Configure the EVAL-AD7616-SDZ resistors (on the back) as follows:

   Jumper/Solder link	Position	Description
   SL1	Unmounted	Channel Sequencer Enable
   SL2	Unmounted	RC Enable Input
   SL3	Unmounted	Selects 1 MISO mode
   SL4	Unmounted	Oversampling Ratio Selection OS2
   SL5	Mounted	If mounted, selects serial interface
   SL6	Unmounted	Oversampling Ratio Selection OS1
   SL7	Unmounted	Oversampling Ratio Selection OS0
   LK40	A	Onboard 5V power supply selected
   LK41	A	Onboard 3.3V power supply selected

   Note

   The configuration above selects the serial interface (SL5 mounted). To use the parallel interface instead, unmount SL5.

5. Connect Micro-USB cable to the UART connector on the ZC706 and to your host PC

6. Connect Micro-USB cable to the JTAG connector on the ZC706 and to your host PC

7. Connect the power supply to the ZC706

8. Connect a 7 V to 9 V DC power supply to the EVAL-AD7616SDZ power jack (J7)

9. Ensure both boards share a common ground connection

10. Build the HDL project:

    1. Verify you have the correct version of Vivado installed. The supported version is listed on the HDL releases page.

    2. Build the HDL project to generate the system_top.xsa file using the Build an HDL project guide.

       Important

       The make command varies based on the interface you want to use:

       • Serial interface:

       $ make SER_PAR_N=1
       

       • Parallel interface:

       $ make SER_PAR_N=0
       

11. Refer to the AD7616 No-Os Example Project for instructions on how to build and run the no-OS project on the ZC706.

12. Turn on the power switch on the ZC706

13. Observe console output messages on your terminal (use the first ttyUSB or COM port registered)
