Still, in view of our experiences with the AutoFocus project we are optimistic that such tools can be built. Although we do not yet have enough experience with industrial-size projects, we obtained satisfying results with some core aspects of such systems (deployment of systems on 4-bit and 8-bit microprocessors, schematic introduction of security aspects, custom scheduling algorithms to distribute computation effort over time). That the close integration of domain properties into CASE tools is feasible has been demonstrated, for example, for simultaneous engineering in process automation.
