Q-DOT Selects Sequence's Columbus-AMS RLC Parasitic Extraction Tool

10/12/2004 - Sequence Design announced that Q-DOT, a company advancing the state-of-art in data conversion, signal processing, and communications, has selected Sequence's RLC Parasitic Extraction tool - Columbus-AMS - for inductance and capacitance extraction.

"Designing mixed-signal circuits well into the microwave region requires exceptional modeling to ensure first-pass success. Prior to using Columbus-AMS, inductance for critical circuit areas was manually calculated. Other tools did not provide the accuracy or ease-of-use required," said Don Herman, director of engineering for Q-DOT, Inc. "This caused numerous painstaking and time-consuming iterations as we identified and analyzed potential problems one small area at a time. But, with Columbus-AMS, inductance and capacitance are quickly and easily extracted for the entire design. This provides insight into potential oscillation and ringing without having to guess where the problems might originate. Columbus-AMS agrees well with our manual inductance calculations and return path analyses, providing the accuracy we need. And, it integrates cleanly into our design flow. Our engineers were able to get Columbus-AMS running and analyze a thorny mixed-signal circuit problem in a couple of weeks, after months of manual analysis."

Parasitic interconnect inductance becomes more prevalent on complex 130 nm circuits due to tightly packed clock trees and power grids, which in turn affect performance and yields. Even small inductances can cause 100+ GHz devices to oscillate. Sequence's Columbus-AMS inductance-modeling methodology has demonstrated greater success on mixed-signal and high-speed analog designs than traditional inductance parasitic approaches. Sequence's patented technology in this area has delivered unparalleled accuracy for ASIC and mixed-signal design houses worldwide.

"Today's high frequency designs must extract inductance or risk design failure," said Rob Mathews, vice president of product marketing, Sequence Design. "Q-DOT tested the limits of our tool. Their bleeding-edge development gives us a sense of where the future of design is going."
