This document presents the steps to setup an environment for using the EVAL-AD5415SDZ evaluation board together with the Xilinx KC705 FPGA board, the Xilinx Embedded Development Kit (EDK) and the Micrium μC-Probe run-time monitoring tool. Below is presented a picture of the EVAL-AD5415SDZ Evaluation Board with the Xilinx KC705 board.
For component evaluation and performance purposes, as opposed to quick prototyping, the user is directed to Analog Devices System Demonstration Platform (SDP). The SDP consists of a:
The EVAL-SDP-CB1Z controller board is part of Analog Devices SDP providing USB 2.0 high-speed connectivity to a PC computer running specific component evaluation software. Each SDP evaluation daughter board includes the necessary installation files needed for this performance testing. It's expected that the analog performance on the two platforms may differ.
Below is presented a picture of SDP-B Controller Board with the EVAL-AD5415SDZ Evaluation Board.
The AD5415 is a CMOS, 12-bit, dual-channel, current output digital-to-analog converter. This device operates from a 2.5 V to 5.5 V power supply, making it suited to battery-powered applications and other applications. As a result of being manufactured on a CMOS submicron process, this part offers excellent 4-quadrant multiplication characteristics, with large-signal multiplying bandwidths of 10 MHz.
The EVAL-AD5415 evaluation board is designed to help customers quickly prototype new AD5415 circuits and reduce design time. The board requires ±12 V and +5 V supplies. The +12 V VDD and −12 V VSS are used to power the output amplifier; the +5 V supply is used to power the DAC (VDD) and transceivers (VCC).
The first objective is to ensure that you have all of the items needed and to install the software tools so that you are ready to create and run the evaluation project.
The following table presents a short description the reference design archive contents.
Folder | Description |
---|---|
Bit | Contains the KC705 configuration file that can be used to program the system for quick evaluation. |
Microblaze | Contains the EDK project for the Microblaze softcore that will be implemented in the KC705 FPGA. |
Software | Contains the source files of the software project that will be run by the Microblaze processor. |
uCProbeInterface | Contains the uCProbe interface and the .elf symbols file used by uC-Probe to access data from the Microbalze memory. |
Before connecting the ADI evaluation board to the Xilinx KC705 make sure that the VADJ_FPGA voltage of the KC705 is set to 3.3V. For more details on how to change the setting for VADJ_FPGA visit the Xilinx KC705 product page.
At this point everything is set up and it is possible to start the evaluation of the ADI hardware through the controls in the uC-Probe application provided in the reference design.
Launch uC-Probe from the Start → All Programs → Micrium → uC-Probe.
Select uC-Probe options.
Set target board communication protocol as RS-232
Setup RS-232 communication settings
The following figure presents the uC-Probe interface that can be used for monitoring and controlling the operation of the EVAL-AD5415 evaluation board.
Section A is used to activate the board and monitor activity. The communication with the board is activated / deactivated by toggling the ON/OFF switch. The Activity LED turns green when the communication is active. If the ON/OFF switch is set to ON and the Activity LED is BLACK it means that there is a communication problem with the board.
Section B is used to control the state of the hardware pins (CLR and LDAC).
Section C is used to call the clear functions (clear DAC output to zero scale or to midscale).
Section D is used to change the bits from the Control Register. After any change of the buttons position is necessary to press the (Send Control Bits button.
Section E is used to load, update and read the DACs registers.
In case there is a communication problem with the board the follwing actions can be perfomed in order to try to fix the issues:
