generate waveform output on FPGA

I am trying to store a sampled waveform onto FPGA, which I could then output to feed a chip. Previously, the number of samples was relatively small (approx 150k). But I now need to store about 3 m...

You didn't say anything about your sampling rate etc.

Yes, if your sampling rate is low, you could read the ADC with a NIOS and write a text file to SDRAM, then read it and write it out to the DAC.

But you might find it overall simpler to use binary data with one DMA block to read from the ADC, and another DMA to write to the DAC.
