I'm also interested in this question. I was exposed to the use of
dSpace on one project a year-and-a-half ago. A fellow working on the
project wrote a C-language S-file, then had to modify it painstakingly
to work with the dSpace compiler (because the compiler didn't support
all of the M** constructs, particularly wrt memory management). He had
an awful time, because there were essentially no debugging tools. He
had to debug the code via conditional exits, with each compile-and-run
cycle taking ~15 minutes. That was hideous.
Hopefully, both dSpace and xPC Target are better than this now, but I'd
like to know for sure.

I have been using xPC for about two years on data acquisition and control.
We also have many copies of dSPACE here. I have found xPC very easy to use
and customize. I have built up two large hardware-in-the-loop vehicle
driveline simulators using xpc. The system uses a desktop PC as the target
with A/D, CAN, D/A, DIO, T/C, RS232 (lots of I/O). I originally intended to
use dSPACE, but found the extra cost too much to bear. Also dSPACE would
not respond to my requests for CAN (J1939) support. I got all the support
that I needed from Mathworks on xPC. We have also built up several xPC
systems that use PC/104 hardware. One system uses a lot of I/O (4 CAN
channels, 16 A/D, 8 D/A, DIO, Timer/Counters, etc). The I/O library was
included with xPC and is very easy to configure! I have easily written
special s-functions for use with xPC. The use of Watcom and Visual C++ makes
You can think of your watch list as threads that you have bookmarked.
You can add tags, authors, threads, and even search results to your watch list. This way you can easily keep track of topics that you're interested in. To view your watch list, click on the "My Newsreader" link.
To add items to your watch list, click the "add to watch list" link at the bottom of any page.
How do I add an item to my watch list?
To add search criteria to your watch list, search for the desired term in the search box. Click on the "Add this search to my watch list" link on the search results page.
You can also add a tag to your watch list by searching for the tag with the directive "tag:tag_name" where tag_name is the name of the tag you would like to watch.
To add an author to your watch list, go to the author's profile page and click on the "Add this author to my watch list" link at the top of the page. You can also add an author to your watch list by going to a thread that the author has posted to and clicking on the "Add this author to my watch list" link. You will be notified whenever the author makes a post.
To add a thread to your watch list, go to the thread page and click the "Add this thread to my watch list" link at the top of the page.

What are tags?
A tag is like a keyword or category label associated with each thread. Tags make it easier for you to find threads of interest.
Anyone can tag a thread. Tags are public and visible to everyone.
The newsgroups are a worldwide forum that is open to everyone. Newsgroups are used to discuss a huge range of topics, make announcements, and trade files.
Discussions are threaded, or grouped in a way that allows you to read a posted message and all of its replies in chronological order. This makes it easy to follow the thread of the conversation, and to see what’s already been said before you post your own reply or make a new posting.
Newsgroup content is distributed by servers hosted by various organizations on the Internet. Messages are exchanged and managed using open-standard protocols. No single entity “owns” the newsgroups.
There are thousands of newsgroups, each addressing a single topic or area of interest. The MATLAB Central Newsreader posts and displays messages in the comp.soft-sys.matlab newsgroup.
How do I read or post to the newsgroups?
You can use the integrated newsreader at the MATLAB Central website to read and post messages in this newsgroup. MATLAB Central is hosted by MathWorks.
Messages posted through the MATLAB Central Newsreader are seen by everyone using the newsgroups, regardless of how they access the newsgroups. There are several advantages to using MATLAB Central.
Your MATLAB Central account is tied to your MathWorks Account for easy access.
Use the Email Address of Your Choice
The MATLAB Central Newsreader allows you to define an alternative email address as your posting address, avoiding clutter in your primary mailbox and reducing spam.
Most newsgroup spam is filtered out by the MATLAB Central Newsreader.
Messages can be tagged with a relevant label by any signed-in user. Tags can be used as keywords to find particular files of interest, or as a way to categorize your bookmarked postings. You may choose to allow others to view your tags, and you can view or search others’ tags as well as those of the community at large. Tagging provides a way to see both the big trends and the smaller, more obscure ideas and applications.
Setting up watch lists allows you to be notified of updates made to postings selected by author, thread, or any search variable. Your watch list notifications can be sent by email (daily digest or immediate), displayed in My Newsreader, or sent via RSS feed.
