Hi Kidneta,

there are two answers to this:

1) One is to use a direct link to jtagatlantic. Unfortunately AFAIK this very interesting module is NOT OFFICIALLY documented by Altera. You can however use this functionality in a restricted way. Please refer to the discussion on this subject (http://www.alteraforum.com/forum/showthread.php?t=2199&page=2). This allows to write our PC-host application e.g. in C code.

2) The second is to use the new Altera QSYS tool instead of SOPC. This tool allows you for making a user application and GUI interface using tcl scripts.

Please correct me if I am wrong/incomplete...
