Telasic Selects Sequence Columbus-RF for Extraction Tool

4/10/2003 - When TelASIC Communications, founded to deliver high-performance and cost-effective silicon to the wireless marketplace, started searching for an extraction tool the design team had two major requirements: the ability to extract inductance parasitics, and a more automated approach to the extraction process.

The company's design flow is based on Cadence's Analog Artist and Spectre RF simulator. What was missing was an extraction technology that could handle resistance, capacitance, and inductance, all the while being coordinated with the IBM SiGe design kits. According to TelASIC CTO, Don Devendorf, it is essential to have RLC extraction when working with SiGe because of the high speeds achieved.

After careful evaluation, Devendorf settled on Sequence Design's Columbus-RF, the only tool that met all of the company's requirements.

Before adopting Columbus-RF, parasitics at TelASIC were painstakingly extracted by hand according to Devendorf. "Designers had to focus on identifying the most sensitive nodes and had to calculate around those nodes. It took a lot of time and was error prone.

"There was no commercial tool capable of dealing with inductance until Sequence came along," Devendorf said. "Columbus-RF been very helpful, providing an excellent correlation to aberrant behavior, and it's allowed us to work on problems we would have been in the dark on in the past . . . we're delighted to have it."

"A highly skilled group like this runs into some pretty thorny design issues," said Will Ruby, Sequence director of product marketing. "The fact that TelASIC has chosen Columbus-RF points out just how much value we, and our customers, place on these tools."
