In the past, virtual prototyping technologies simply did not deliver the right answers in time to impact the ongoing design process. Very often, CAE has been used for design verification and has run almost outside the process - not as a proactive design optimization tool. Raw processing speed has not been the real bottleneck. The fundamental problem lies with the lack of accurate system-level prediction technologies and with the sheer number of different software tools that are in use at many companies today. A lot of time is lost in non value-added engineering effort - dealing with many barely compatible software tools for just one attribute at a time, transferring data from one environment to another, rebuilding models, and remeshing.
