You can get a TCI6482 DSK board:

and use that to run your actual code and socket I/O. Since you already have
operational code, this makes way more sense then trying to deal with the simulator --
and you should get more accurate results.

The TCI6482 is a single-core device (also called C6455); your Node B system is using
TCI6488 (3 cores). Hopefully you can extrapolate your results from one core.

Ok that makes me laugh. "Nobody has a clear understanding of [CCS] function." Join
the club :-)

Seriously, CCS is a sophisticated, advanced far and away one of the best
embedded device IDEs ever created. But it's more robust with actual hardware than
with complex software simulation, due to all the years of usage and bug reporting by
1000s of developers using TI chips.
