Agilent Technologies Inc. has announced breakthroughs in its core electronic design automation (EDA) frequency-domain simulation technologies for fast and accurate RFIC, MMIC, and RF system-in-package (SiP) designs. Simulation speed improvements of up to 50 times have been achieved for large and complex circuits used in wireless communications products and aerospace and defense applications.

In RFIC, MMIC and RF SiP development, a single design iteration can cost up to a million dollars. The simulation technology breakthroughs in Agilent's EDA software will help eliminate these costly iterations by allowing designers to quickly and accurately predict performance prior to fabrication.

"Our customers' designs are continually becoming larger and more complex, so we have been investing heavily in our core RF simulation technology," said Larry Lerner, research and development manager of Agilent's EEsof EDA Division.

Customers have observed excellent results with test circuits containing thousands of transistors, such as transceiver ICs for wireless local area network (LAN) applications, according to Agilent. Extracted view simulations, which include additional physical components that represent IC parasitics, have been successfully completed on circuits containing hundreds of thousands of these components. In some cases, these circuits could not be simulated with previous technologies. Now, these large and complex circuits simulate and converge quickly, even when using default simulation settings.

Agilent's enhanced simulation technologies will be included in the company's next release of its ADS and RFDE simulation software packages. The enhanced simulators in ADS and RFDE are expected to be available to selected beta-test customers beginning in June 2005.
