EMC Question of the Week: October 4, 2021
IBIS is a standard file format for characterizing a digital component's
- inputs and outputs
- power bus noise
- heat dissipation requirements
- conducted emissions
Answer
The correct answer is “a.” IBIS or Input/Output Buffer Information Specification is a standard method for conveying information about the electrical behavior of a digital device's inputs and outputs without revealing proprietary information about the interface design. IBIS models include information related to the electrical properties of the on-die circuitry as well as package parasitics. IBIS models are widely used for signal integrity modeling, but also provide information that can be helpful for making EMC-related design decisions.
