Early work we did here was based on an outside tool wherein we defined parts & then "compiled" the diagrams based on the internal format for storing the diagrams. This tool eventually gave way to one that was entirely home grown by one of our sister-organizations, Hamilton Standard. I have not looked at any commercial tools recently since my involvement in the project is now more one of "end user" rather than "developer" (Everyone should be forced to do this at least once! ;-) There may be something out there which would fit the bill, but the requirements are that it support what our logic designers are used to (sort of) - control laws diagrams. (we also support a general flowchart-ish format). For new projects, it might be possible to undertake some whole new format of diagram, but it would have to support the kind of things that logic designers do. (I'm also getting too old and cranky to try to once again start pleading with them to try something new!) The real value of the tool was that we took diagrams which the designers were going to draw anyway and formalized it enough that code could be automatically produced from the diagrams. That and being able to configuration manage/change control the whole thing meant substantial automation of an otherwise labor intensive process.
