Modeling Non-Linear Behavior of Analog Circuits


ASCEND is the name of a software code that models the behavior of non-linear analog electrical circuits. As the complexity and performance criteria of analog and mixed-signal systems are steadily increased, behavioral modeling methods are commonly used by design engineers for rapid higher-level simulations. Behavioral models have the potential of faster simulation speed without loss of accuracy for given performance specifications.

ASCEND has the unique ability to model the non-linear behavior of circuits. Non-linear dynamic effects can be included in ASCEND models, greatly improving the simulation results of circuits that are highly dependent on such behavior to achieve their function.

ASCEND offers a method of accelerating the development of electronic circuits designed using simulation. ASCEND uses an automated procedure from circuit description in SPICE format to the behavioral model, saving time and reducing errors.

ASCEND advantages:

  • Provides highly accurate models of a wide variety of circuits,

  • An advantageous tradeoff capability between accuracy versus speed,

  • Rapid generation of models (on the order of half an hour),

  • Is the only method that directly addresses non-linear behavior.
