Can FPGA outputs be read back to Quartus or Matlab?

[Altera_Forum]

I've designed a demodulator using HDL. The input data is stored in lpm_rom, mif file generated by matlab. I want to verify the output in matlab too after the design is programmed in FPGA, is there a way to do that?  

How can I store the output signal in a lpm_ram or something that can be read back to Quartus2, then import to matlab for analysis?

It's easily done with the MegaWizard. Or use SignalTap and export the data to a file.

I want to store the outputs in the RAM then export it for Matlab. Does it make sense to log the output in RAM andread back in Matlab, even if the design is running in FPGA? I haven't used system memory editor before

I don't see a principle difference between acquisition with Signaltap and a user design based on internal memory, neither in terms of available RAM capacity nor data transmission speed, as long you are using the JTAG interface to transmit the data. If you intend to use other interfaces, the user design can be faster, but would also involve more effort.
