Comments on CASE tools and integrated development packages?

[John O'Beck]

I recently attended a seminar on IDE's C development environment.  This
is a Suite of packages integrated to provide a cohesive development
environment from writing requirements down to debugging and maintaining code.

The high level requirements, analysis and design are done with Software
Through Pictures (STP).  Coding debugging etc is provided via Saber-C,
Hardcopy output is provided via Framemaker.

Has anybody out there had first hand experience with this package?

Would anyone care to recomend other CASE tools that should be looked at?
Experience with these other tools?

Thanks
