Both are critical to achieving design success. Given today's increasing clock speeds, system complexities, and reduced time to market, accurate package models can not wait until prototype measurements can be made. If you wait, you are too late. The tool is named LC because it delivers the equivalent-circuit parameters of inductance and capacitance for of 3D components. LC is a revolutionary tool for technology pioneers, it teaches the user about their technology enabling early and accurate characterization, understanding and application of key system technologies.
Time domain is the world of the packaging engineer.
Modeling and visualizations in the time domain inherently enhances the intuitive understanding of the complex electrodynamics and the relationships between the temporal and spacial domains. Reflections are completely modeled and easily understood. Capacitance from the Electric field, and inductance from the Magnetic field as show below. All field and parametric representations within LC can be plotted in the frequency domain using LC's built-in DFT capabilities. Self inductance is simply the ratio of magnetic flux generated, divided by the amount of current that created that flux.
