Altera supplies the "Host-Based File System" (altera_hostfs) that allows your NIOS HAL-based software to fopen()/fwrite() files that reside on your PC (while connected through JTAG, obviously). You can use this for the temporary kind of logging/debugging it sounds like you are trying to accomplish.

The Altera System Console also provides services for transferring data to/from your target which may be better suited if you are trying to construct an in-hardware test environment. See http://www.alterawiki.com/wiki/system_console_byte_stream_example for one example.
