Hello,
See the note in the wiki you referenced;
http://processors.wiki.ti.com/index.php/XDM_GenAlg_Wizard_FAQ#From_CCS_Eclipse
---
If you enable XDAIS in your CCS Eclipse environment (Window | Preferences | CCS | RTSC | Check the version of XDAIS you want to use), you will have a new "Tools | XDAIS Tools | GenAlg" menu item, as shown in the image to the right.
(Note that in CCS v5.1, the Tools menu only appears when CCS is in CCS Debug Perspective.)
---
It looks like your are in the CCS Edit perspective.
Thanks
