Agilent Technologies Inc. has developed the EMDS-for-ADS, an integrated design flow solution that includes full 3D electromagnetic (EM) simulation for RF Module Design.

The full 3D EM simulator is integrated into Agilent's Advanced Design System EDA software platform and eliminates the need for standalone EM tools.

EMDS-for-ADS helps designers accurately predict the 3D EM interactions of embedded passive components in RF modules while co-simulating with active circuits to maximize the wireless sub-system performance. The integrated 3D EM simulator improvements allow designers to analyze larger circuits faster without leaving their familiar design flow. This capability increases productivity in the overall design and verification process.

"The 3D EM simulator allows our RF module designers to replace standalone tools such as HFSS," said Bob Wong, R&D engineer with Agilent's component test (network analyzer) division. "As a result, we've more than doubled our design efficiency because we can interactively co-simulate the circuit and physical 3D effects without leaving the ADS design flow."

EMDS-for-ADS accounts for the finite dielectric boundaries of RF modules. In addition, it is useful for verifying the accuracy of faster Planar EM simulators such as Agilent's Momentum, which assumes infinite dielectric planar layers in its analysis. In addition, EMDS-for-ADS features a new finite element mesher and high-capacity iterative solver that delivers better accuracy, speed and capacity for RF system-in-package and RF module designs.

The most common applications for EMDS-for-ADS are RF modules based on low temperature co-fired ceramics and laminates with embedded passive structures. They are found in almost all RF modules produced today. EMDS-for-ADS saves time when drawing these structures with its planar RF layout macros. These macros automatically draw RF components such as spiral inductors and meander lineswhich are time-consuming to construct using a generic 3D drawing and simulation tool.

EMDS-for-ADS is part of the new Agilent Advanced Design System 2008 Update 2. Advanced Design System is a powerful electronic design automation platform, offering complete integration to designers of consumer and commercial wireless electronic products such as mobile phones, wireless networking and GPS, as well as radar and satellite communications systems, and high-speed digital serial links.

EMDS-for-ADS and ADS 2008 Update 2 is available now, with prices starting at approximately $18,000. It is also available in time-based bundles with ADS, starting at approximately $20,000 per year.
