Modular macromodeling techniques for Spice simulators

摘要

Spice-absed circuit simulation has become common in the last few years as software products become more user-oriented and desktop computers be-come more powerful. More engineers are now able to perform more complex circuit simulations than ever before. These capabilities have the potential to provide tremendous benefits for the design and verification of electronic circuits and systems. The usefulness of Spice extends far beyond its original intended purpose of IC design. Unfortunately, techniques for modeling electronic parts have not kept pace with other advances. Commercially available Spice programs have added greater mathematical capabil-ity and flexibility. Faster computers have reduced the importance of model computational efficiency. Electronic-part functions have become more modular and complex, requiring more complex models to accurately simulate them. Users depend on manufacturers to build many of the models they use, but the manufacturers often don't provide them.
