Agilent improved the accuracy of time domain response in high frequency spice simulation software

Agilent has announced it has achieved a breakthrough in high frequency SPICE simulation technology in displaying accurate time domain response. This will help to design boards at data-rates higher than 1Gbps faster. Agilent has developed new convolution simulator, which can automatically enforce passivity on S-parameter models and determine accurate causal time domain response.
The feature packed software called, Advanced Design System EDA software provides complete set of front-to-back simulation and layout tools and instrument links for RF and microwave IC design in single flow. Agilent says, this software can model entire serial data links, including interconnects, pre-emphasis and adaptive equalization in the presence of non-linear driver and receiver models.
The other important features offered are,
A set of IBIS (I/O Buffer Information Specifications) models for single-ended and differential components such as sources, buffers, and terminations. IBIS models show how the circuits behave when triggered by waveforms. With IBIS models, designers don't need transistor level details of components.

There is a Broadband spice model generator to automatically process frequency-domain data produced by electromagnetic structure simulators such as Agilent's Momentum, EM simulator.
