Simulation as an Essential Tool - Steve Sandler - AltiumLive 2020



This session presents the essential role of simulation in the design and development ecosystem. The speaker draws on his own experience and shares some of his own simulation and the results to answer the fundamental questions. WHY do I need to simulate? WHAT should I simulate? And what is the recommended workflow for efficient simulation? With a focus on SPICE simulation, some of the limitations of SPICE are also discussed.
