I am posting this on behalf of an associate. Please don't flame me if it's too commercial, or not relevant, or the spelling is bad, or too long, or ...

CASEworks/RT is a full coverage, fully integrated CASE toolset intended for cross development of complex real-time embedded systems. CASEworks/RT includes Framework/RT, a requirements and design tool, CopyCat, a target system simulator, Remedy, a cross development source and system level debugger, various utilities, and the Unison Real-Time Operating System. The Unison Real-Time Operating System offers real-time multiprocessing and message passing using either the Reliant executive or the pSOS+ executive (an emerging industry standard for VME). Unison offers 4.3BSD compatibility at the file I/O and networking level to ease porting of applications and simplify programming, and a broad set of off the shelf device servers. Unison comes with standard ports for various VME cards (eg. Ironics 3220, Motorola 147, ...) and where off the shelf solutions do not exist, Unison is user portable to a broad set of additional hardware . In this case, you could initially develop on your AT using CopyCat, Unison/Reliant-86 and Turbo C under MS-DOS. To evolve the environment into an MC68K multiprocessor environment on VME would only require building a target specific configuration (off the shelf with standard cards), recompilation and relinking your application with CrossCode C, and downloading and running your program using the support tools and/or the Remedy debugger. Other features available are: complete requirements and design tools, automatic code generation, flesh editing, performance estimation, TCP/IP networking, DECnet, and 29K support. Universities receive a 75% discount from list prices. Support for CASEworks/RT exists for Sun 3, Sun 4, MS-DOS, Ironics P32A, and VMS.
