The book comes with a CD-ROM that includes demos for Rhapsody, a "fully constructive UML Visual Programming Tool" and TimeWiz, an "integrated tool for timing analysis." The former is a competi tor to Rational Rose. The latter performs timing and schedulabili ty analysis. Douglass is the Chief Evangelist for i-Logix, the devel- oper of Rhapsody. Both demos are crippled versions that will not save your work. I walked through the tutor- ial for Rhapsody. It looks promising. The statechart animation and debug- ger is by far the most interesting fea- ture. I don't have one of the support- ed C++ compilers (Visual C++ 4.0 and 5.0, Borland C++ 5.0.2, Tornado 1.0, pRISM+ PPC 2.2.2, or pRISM+ 2.2.6) and was unable to try it out. The instal- lation notes indicate that the demo version does not have statechart ani- mation, only the high-end develop- ment package. Disappointing choice. Both Rhapsody and TimeWiz require a significant investment of time to use properly. I suppose you could enter an already worked out project just to evaluate them. I'd want to road test something like this over the lifetime of a small project before committing a fu ll-blown project to it. My suggestion to manufacturers is limit the size of the model, not the capabilities or use time. It isn't many projects, even toy or personal ones, that can be completely developed and the documentation updated in 30 days (or however long you can keep the program running without exiting) . Overall I like this book and intend to consult it on a regular basis. It is a book for working software developers (people who are already "doing hard time"), not undergraduate computer science students. Following its advice is a lot of work up front to save time in the long run. To appreciate it, you have to have already experienced that "quick and dirty" isn't quick. The mark of a great book is how it holds up over the long haul. By this measure, Doing Hard Time is a very good book. Having read it through Embedded Systems Programming SEPTEMBER 2000 203 once, it now sits on the bookshelf next to my workstation for road testing. It's going to take a year or two of use to fully absorb. My preliminary judgment is that if you write software with multi- ple concurrent inputs and you are looking for a better way to build soft- ware, read this book. esp Jeffrey L. Taylor has been a software engi- neer for over 25 years. About half of this time has been devoted to embedded and real-time systems. His current research areas are open source software, Linux, and soft- ware development. He may be reached at jeff taylor@ieee. org.
