It seems that Ready Systems' CARDtools has become the de facto
standard CASE tool for real-time embedded system and software design
at my company.  I have two questions for anyone who has used this package:

1.  What design method does it support?

        Possible answers I've come up with are
        
        a)	Hatley, sort of
        b)	Ward-Mellor, sort of
        c)	Ready Systems' own
        d)	anyone/everyone's (it's just a tool box)
        
        TFM doesn't say what method is supported; neither does is have
        any references listed that would give it away.  When I read TFMs
        I get the feeling that the answer is d), but this is never stated.
        When I ask people here what method they use with CARDtools they say,
        "Well, just CARDtools, right?"  A recent article in Computer Design
        magazine just said CARDtools supports Ward-Mellor, without really
        saying how.

2.  (really a general CASE question)  Is there any size of project for
    which use of tools like CARDtools is uneconomical?

Followups to comp.realtime please.
