Exar Teams with Sequence on Comms IC Excellence

10/4/2002 - The switch to Columbus-RF, Sequence Design's high-accuracy parasitic extraction software for mixed-signal and digital circuits, has delivered time-to-market and improved critical timing analysis for communications IC leader, Exar.

"Using Sequence's Columbus-RF extraction back-annotated simulations has given Exar a time-to-market advantage when compared to schematic simulations without LPE," according to Dr. Roubik Gregorian, executive vice president and general manager, Communications Division, and CTO of Exar, a Fremont, Calif.-based provider of high-performance, mixed-signal silicon solutions for the worldwide communications infrastructure. "The Columbus-RF accuracy of extracted and simulated results has been validated in actual silicon."

"Exar's experience is further evidence that parasitic effects on circuits cannot be ignored," according to Dr. Susheel Chandra, Sequence senior vice president of R&D and product marketing. "All parasitics - inductance, capacitance and resistance - must be extracted with high accuracy in order to confidently predict circuit behavior in high-frequency RF, optical equipment, and high-speed digital designs."

Exar has employed Columbus-RF on a number of sophisticated designs over the past two years, ranging from a 0.18-micron to 0.35-micron for its networking IC designs.

Another benefit was the ability to integrate the Sequence tools quickly. It took using only a two-page description of Columbus-RF, and a couple of questions, for Exar to be off and running.

About Columbus-RF
Columbus-RF is part of Sequence's ExtractionStage, a suite of high-performance EDA tools tuned for complex multi-million-gate SoCs (systems-on-a-chip) and analog/mixed-signal design. ExtractionStage is the only suite of automated interconnect parasitic tools extracting highly accurate (results correlated within a few percent of a field solver) resistance, capacitance and inductance values across a wide range of design styles.

Columbus-RF is the industry's first integrated, 3-dimensional RLC interconnect extraction solution specifically tailored for RF, analog and custom high-speed digital IC designs. The product allows RF designers to reduce risk and uncertainty in their high-performance designs, and avoid unpleasant surprises and re-spins. Columbus-RF provides tight integration with Cadence's Analog Design Environment and Diva physical verification tools.

The product has experienced significant sales growth in the past two years, gaining more than 20 customers since its release. IBM includes Columbus-RF in its SiGe design kits, and Exar, Qualcomm, Valence, and LeCroy are among a growing list of customers using the product.

Columbus-RF was recently chosen by the readers of Wireless Systems Design as the best wireless design tool for 2002.
