• Contains continuous-time modeling components called “event generators and “waveform generators”.

This library is used to define systems such analog circuits, mechatronics and control systems that require a continuous behavior. The basic library block is an integrator which serves the unique role of wiring up the ODE. All other blocks in the library are stateless, the state being maintained by the Integrator.  The library contains waveform generators, step size controller, stateful memory, event generators and integrator blocks.  In addition the library also contains samplers, transfer function, differential systems, state space, integrator, zero crossing detectors, zero hold and threshold monitors.

Embedded systems frequently contain components that are best modeled using differential equations, such as MEMS and other mechanical components, analog circuits, and microwave circuits. These components, however, interact with an electronic system that may serve as a controller or a recipient of sensor data. This electronic system may be digital. Joint modeling of a continuous subsystem with digital electronics is known as mixed signal modeling.
