Below is presented a picture of the EVAL-AD5446SDZ Evaluation Board with the Xilinx KC705 board. Rev 05 Feb 2014 17:42 | Page 1 For component evaluation and performance purposes, as opposed to quick prototyping, the user is directed to use the part evaluation setup. This consists of: 1. A controller board like the SDP-B ( EVAL-SDP-CS1Z) 2. The component SDP compatible product evaluation board 3. Corresponding PC software ( shipped with the product evaluation board) The SDP-B controller board is part of Analog Devices System Demonstration Platform (SDP). It provides a high speed USB 2.0 connection from the PC to the component evaluation board. The PC runs the evaluation software. Each evaluation board, which is an SDP compatible daughter board, includes the necessary installation file required for performance testing. Note: it is expected that the analog performance on the two platforms may differ. 28 Sep 2012 09:32 * Adrian Costina Below is presented a picture of SDP-B Controller Board with the EVAL-AD5446SDZ Evaluation Board. The AD5446 is a CMOS 14-bit current output, digital-to-analog converters (DACs). Operating from a single 2.5 V to 5.5 V power supply, these devices are suited for battery-powered and other Rev 05 Feb 2014 17:42 | Page 2 applications. The EVAL-AD5446 evaluation board is designed to help customers quickly prototype new AD5446 circuits and reduce design time.

For more details on how to change the setting for VADJ_FPGA visit the Xilinx KC705 product page. Use the FMC-SDP interposer to connect the ADI evaluation board to the Xilinx KC705 board on the FMC LPC connector. Connect the JTAG and UART cables to the KC705 and power up the FPGA board. To power on the EVAL-AD5446 evaluation board, you need to apply 12V differential voltage to J6 connector on the board. Reference Project Overview The following commands were implemented in this version of EVAL-AD5446 reference project for Xilinx KC705 FPGA board. Command Description help? Displays all available commands. Writes to the DAC register. Accepted values: register= 0 .. 16383 - the value written to the DAC. register? Displays last written value in the DAC register. Sets the DAC output voltage. Accepted values: voltage= -10000 .. 0 - desired output voltage in milivolts. voltage? Displays last written voltage value to the DAC. Commands can be executed using a serial terminal connected to the UART peripheral of Xilinx KC705 Rev 05 Feb 2014 17:42 | Page 4 FPGA. The following image shows a generic list of commands in a serial terminal connected to Xilinx KC705 FPGA's UART peripheral. Software Project Setup The hardware platform for each reference projects with FMC-SDP interposer and KC705 evaluation board is common. The next steps should be followed to recreate the software project of the reference design: First download the KC705 Reference project from Github on your computer. You can do this by clonning this repository: https://github.com/analogdevicesinc/fpgahdl_xilinx. Rev 05 Feb 2014 17:42 | Page 5 From this entire repository you will use cf_sdp_kc705 folder. This is common for all KC705 projects. Open the Xilinx SDK. When the SDK starts, it asks you to provide a folder where to store the workspace. Any folder can be provided. Make sure that the path where it is located does not contain any spaces. In the SDK select the FileImport menu option to import the software projects into the workspace. In the Import window select the GeneralExisting Projects into Workspace option. In the Import Projects window select the cf_sdp_kc705 folder as root directory and check the Copy projects into workspace option. After the root directory is chosen the projects that reside in that directory will appear in the Projects list. Press Finish to finalize the import process. Rev 05 Feb 2014 17:42 | Page 6 The Project Explorer window now shows the projects that exist in the workspace without software files. Now the software must be added in your project. For downloading the software, you must use 3 links from Github given in Downloads section. From there you'll download the specific driver, the specific commands and the Xilinx Boards Common Drivers(which are commons for all Xilinx boards). All the software files downloaded must be copied in src folder from sw folder. Before compilation in the file called Communication.h you have to uncomment the name of the device that you currently use. In the picture below there is an example of this, which works only with AD5629R project. For another device, uncomment only the respective name. You can have one driver working on multiple devices, so the drivers's name and the uncommented name may not be the same for every project. Rev 05 Feb 2014 17:42 | Page 7 The SDK should automatically build the project and the Console window will display the result of the build. If the build is not done automatically, select the ProjectBuild Automatically menu option. If the project was built without any errors, you can program the FPGA and run the software application. 13 Aug 2013 08:22 * Lucian Sin More information ask questions about the FPGA reference design Example questions: FMCDAQ2 Arria10GX Nios Sourcecode by kairue Using ZC706 and AD-fmcomms3 by 85083074@qq.com FM-COMMS3 and FM-COMMS5 with VC707 vs Zync ZC706 by dr8 How Xps ip update to vivado ? by huanmolb@163.com AD9361 Data capture using Linux GUI by nidhinki 28 May 2012 14:18 (c) Analog Devices, Inc.
