[ECUArch-gen] RE: ECU_Architect

[Mike P. <pa...@se...>]

Hey Jim,

just very briefly, since I think the main ideas are in in the SF
trackers: the original plan was to create a UML 2 based environment to
allow modeling the logical architecture of an embedded system. The
second step would have been the deployment, i.e. mapping atomic SW units
to ECUs. Eventually, simple forms of code generation could have created
the interface shells for the various systems. (I do not believe too much
in code that is created fully automatically, pure MDA..., even though I
like the ideas a lot...)

Due to the availability of EA I must acknowledge that there now is an
inexpensive tool that in a corporate environment may fit in just a
little better than open source (companies want support, warranties...).
So one thing I could still imagine would be to hook into a tool like EA.
Since it is a pure UML modeler, it obviously lacks a few things one
would like to see in ECU architecture development.

EA comes with pretty nice code generation mechanisms, but those are not
directed at embedded RT systems. Still the application allows for
extension of those as well.

ECU Architect was not really meant to be a "simple UML tool", but to
offer a UML 2.0 based profile for our kind of business. Now I need to
assess whether EA for instance allows for such a profile, whether it is
an environment I like to work with and so on...

Best,
Mike
