Agilent Technologies Inc. has announced the latest member of its repeater model library intended to quickly and accurately solve issues posed by signal distortion in the multigigabit-per-second regime. The retimer solution, available in the company's Advanced Design System 2013 Transient Convolution Element and SystemVue 2013 AMI Modeling Kit, is intended for designing electrical retimers in chip-to-chip, high-speed digital links, the firm indicated.

Up to now, simulation tools used to design in these nonlinear devices have used computationally expensive SPICE techniques such as Newton-Raphson iteration on modified nodal analysis of Kirchoff's current law. With this latest solution, Agilent claims to offer a quick solution based on bit-by-bit channel simulation and the IBIS AMI flow to retimer applications. Unlike SPICE, these techniques include computationally efficient algorithms that include superposition.

Using a prestandard, novel extension to the industry-standard IBIS AMI flow, SystemVue 2013 offers model builders (typically integrated circuit vendors) a tool to build retimer models. The models run in ADS, the tool that IC consumers (typically data center and telecoms equipment manufacturers) use to design these chips into their systems.

Agilent will submit a proposed enhancement to the IBIS Open Forum later this year. The intent is to incorporate the new techniques into a future version of the IBIS standard. This will ensure retimer model portability across EDA tools in future.

In addition, ADS 2013 adds support for power-aware IBIS models and for the Touchstone 2 file format, as well as a Touchstone Combiner that lets engineers build multiport victim/aggressor channel models out of measured data from a four-port vector network analyzer.

Agilent's SystemVue 2013 and Advanced Design System 2013 are available now. Pricing depends on the exact configuration desired.
