Hello to all,
I am working on a test waveform generator project using the Cyclone III starter kit (3C25N). Once synthesized on the FPGA, the waveform will be sent to a DAC so that it can be viewed using an oscilloscope.
I'm using the TI DAC5672 eval module which has a 34-pin header for input.
Is there any way I can physically interface the DAC with the FPGA? I've worked with an FPGA before but never on interfacing a DAC with it. Extensive google searches did not turn up anything useful.
Thanks in advance for the help.

Page 18 of the evaluation board manual;
http://focus.ti.com/docs/toolsw/folders/print/dac5672evm.html Shows the output connector uses 100-mil headers.
The Cyclone III starter kit
http://www.altera.com/products/devkits/altera/kit-cyc3-starter.html uses an Altera HSMC connector.
You need to buy an HSMC break-out board that converts the signals to 100-mil headers.
http://www.terasic.com.tw/cgi-bin/page/archive.pl?language=english&categoryno=78&no=495 These headers are normally shipped with the evaluation boards (at least they were with the Stratix IV boards). Do you have these connectors?
This might work too;
http://www.terasic.com.tw/cgi-bin/page/archive.pl?language=english&categoryno=67&no=218 Then you have to analyze the timing between your FPGA and DAC and setup appropriate TimeQuest timing constraints.
