The Fastest Way from TDR/T or VNA Measurements to Simulations

As the complexity and speed of digital systems increase, modeling the complex high-frequency effects occurring in the high-speed interconnects is becoming an increasingly challenging task, requiring large amounts of design time.

MeasureXtractor™ is an automated model extraction tool, allowing the designer to obtain an accurate measurement based on the SPICE model of the interconnect, with the press of a button. MeasureXtractor will guide you through the data acquisition process, help you acquire TDR/T or VNA S-parameter data, and will automatically produce an accurate model that matches both the time and frequency response of your interconnect.

Losses, dispersion, jitter, crosstalk, and reflections and ringing are predicted accurately, up to the highest frequency of operation of your instrument. Passivity of models must be explicitly enforced during model extraction, and MeasureXtractor model passivity is assured through the proprietary algorithm. This means that interconnect models generated with MeasureXtractor will not artificially amplify the signal, oscillate, or produce non-causal results when used in system-level simulations.

Behavioral Models

Comparison of behavioral and topological modeling approaches

MeasureXtractor produces what is known as a behavioral model. Such a model does not take into account the actual topology of the interconnect, but instead simply aims to accurately represent the time and frequency behavior of the interconnect in the most simulation efficient manner; in the case of MeasureXtractor, that means with the minimum number of components, and guaranteed passivity. Nonetheless, behavioral models can result in longer simulation time, particularly for large interconnect structures.
