Analog Modeling and Simulation
Analog modeling and simulation encompasses the techniques and tools used to predict and analyze the behavior of analog circuits before physical implementation. From foundational SPICE simulation to advanced behavioral modeling languages, these methodologies enable engineers to explore design spaces, validate architectures, and verify performance against specifications with confidence.
Modern analog design relies heavily on simulation at multiple abstraction levels. Transistor-level SPICE analysis provides detailed accuracy for critical circuits, while behavioral models enable system-level verification of complex mixed-signal designs. Understanding when to apply each approach and how to develop accurate models is essential for efficient analog and mixed-signal integrated circuit development.
