    You can perform SignalTap II operations through the QuartusTcl command shell. Generally, SignalTap is using Altera Virtual JTAG functions, that are documented in a respective Megafunction User Guide, but the application specific protocol part is undocumented.

    I think you can tap the data with SignalTapII, after that you can save the data as other format thru "save as" menu command in QII.
