IBIS modeling(1)

Behavioral VS Structural Modeling

1. Behavioral model is just like a black-box, the electrical parameters can be obtained at the terminals, its property follows

• black-box
• no internal information
• S-parameter and IBIS are both behavioral models

2. Structural model utilizes a lot of "structual" information

• Structual models would cover some of internal intellegent information
• Many componies would not release structural models to users or customers
• Most componies prefer behavioral models over structural models

3. Behavioral models can be extracted from structural models, by simulation or measurement.

IBIS is an acronym of I/O Buffer Information Specification.
