MULTIPHYSICS SIMULATION ENHANCES ELECTRONICS SYSTEM DESIGN

摘要

Simulation of electronic circuits and systems has long focused on the analysis of electrical signals: voltage or current waveforms for analog engineers and binary bit patterns for digital engineers. Now that IC density has grown into the billions of transistors, however, on-chip management of power dissipation has become more critical. You must also consider the physics of how that power converts into performance-degrading heat. Verification of system performance and reliability requires analysis of both thermal and electrical conduction, involving modeling of materials that you previously may have ignored, and the physical interaction from a chip to its package and surrounding environment.
