SPICE Model Synthesis

Sonnet’s analysis engine, em, provides a frequency domain solution in the form of S- Y- and Z-parameters. Many time domain simulators, such as traditional SPICE engines, do not have the capability to import frequency domain data, or have problems with efficiency, stability, or accuracy when using frequency domain data.

To address these problems, Sonnet provides the capability to output your frequency domain data into a SPICE-compatible file. You may choose from four different models, depending on your needs. A brief description of each is provided below, and each model is discussed in detail in the sections following.

Pi Model

N-Coupled Line Model

Broadband SPICE Model

Inductor Model Extractor
