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.

Oh man, that's bogus ... but you are right. Attached is the breakout header schematic that was delivered with the Stratix IV GX development kit.
Perhaps the HSMC to GPIO breakout board would be better then. The original poster can download the schematic for that.
