AWR signal-integrity suite links ICs, packages, PCBs

Claiming to provide a "unified platform" for signal integrity analysis at the chip, package, module and PCB levels, Applied Wave Research Inc. is rolling out the AWR SI 2005 design suite, an extension of the company's existing RF design tools.

AWR SI 2005 extends the company's Analog Office tool suite with a richer set of libraries, new extraction models, a new bond wire model, and an ability to handle nets on boards and packages as well as chips, said James Spoto, AWR president and CEO. He said the new tool suite lets users bring in a variety of technology files to handle electrical and physical modeling of IC, package and board substrates.

What's most significant, he said, is the availability of a unified platform that handles electrical and physical design for chips, packages and boards. "Everyone else has separate platforms for chip design versus package design," he asserted. "We have one unified platform, one data model, and one simulation environment to solve that problem."

Analog Office is a front-to-back RF design system that includes analog and RF simulation, physical layout, extraction, process design kits, and integration with mixed-signal design flows from Cadence Design Systems and Synopsys. AWR has its own harmonic balance simulator, and works with Synopsys' HSpice for time-domain simulation.

With AWR SI 2005, one simulation environment can consistently model interactions between the chip, package, and board, Spoto said. "You might have a signal on a chip that's driving a pad, driving a bond wire, and driving a trace on a package," he said. "All of these signal paths have fairly complex models associated with them."

Bringing IC and package design together is the most important thing, Spoto said.

"We typically find that system and package engineers are working together, but the IC guys are working separately on a different platform," he said. "They really have a hard time, with present EDA solutions, electrically communicating with one another. IC and package designers are looking for better ways to codesign, and that's what our product brings to the party."

AWR SI 2005 is available now from Applied Wave Research as a standalone product or add-on to AWR's Analog Office or Microwave Office. Pricing starts at $15,750.
