I/O Buffer Information Specification (IBIS) is a public-domain, industry-standard specification for modeling input and outputs of digital circuits.

Semiconductor vendors may create IBIS models for their products and distribute them for use in IBIS compatible simulators such as Advanced Design System (ADS). IBIS simulation provides faster simulation as compared with equivalent-circuit SPICE models. Using IBIS models, the nonlinear effects of integrated circuit I/O buffers can be modeled faster and more precisely, using vendor supported information.

ADS presently supports the IBIS 4.2 specification. Keysight representatives on the EIA IBIS committees contribute to and track these evolving standards, and help keep Keysight EEsof EDA tools up-to-date.

Product Highlights

  • Native IBIS I/O Models in the ADS Environment
  • Excellent performance and an easy to use intuitive interface

Designers can now place IBIS models directly on the ADS schematic page; connect bias power supply, trigger and load; select the IBIS file; select the pin name; and simulate for time domain performance.

ADS 2006 Update 1 to present is compliant with IBIS components Version 4.2. Follow the link below to download a table giving the list of keywords that are presently supported.

IBIS I/O Models are integrated into the ADS Transient Convolution Element.
