Sign-off analysis results must match measured power, timing, and sustained temperature of integrated circuits. Lack of correlation between simulated and real life behaviour of integrated circuits causes many problems in design cycle. Increasing number of tools involved in sign-off analysis still provides fragmented picture that is far from measured numbers. InVar is the only tool on the market that implements concurrent analysis of power, temperature, timing, and IR-drop. InVar results correlate with measured parameters of physical samples.
Moore's law still remains valid. Reduction of feature size and increase of transistor's count per area impose a great challenge to EDA tools. To keep the speed of growth, industry needs new tools that are aware of new technology. Some effects that used to be “second order” become critical. In particular, designer cannot ignore any more the dependency between power, timing, and temperature. Analysis in fixed operating corners loses correlation as technology moves forward.
