Webcast Archive: Introduction to "EMDS for ADS"

"EMDS for ADS" is Agilent's integration of EMDS, a full 3D FEM solution, into the ADS (Advanced Design System) flow.

This valuable solution provides RF and Microwave engineers the ability to access full 3D EM technology in a flow that is virtually identical to the Momentum 3D planar flow that exists today.

Three different webcasts are available. The July 2007 session shows simulations of various spiral inductors using "EMDS for ADS." The June 2007 session focuses on a demo of the software. The May 2007 session shows a typical application, the simulation of bond wires.

Product Information

Developed with designer of high-frequency/high-speed circuits in mind, Electromagnetic Design System (EMDS) offers a powerful finite-element EM simulator that solves a wide array of applications with impressive accuracy and speed.

By combining fast solution times, efficient memory usage, and powerful display capabilities, Electromagnetic Design System (EMDS) delivers leading price/performance solution to complex high-frequency problems.

Electromagnetic Design System (EMDS) users need very little background in electromagnetic field theory in order to operate and achieve accurate, meaningful solutions.

Key Features and Benefits

Electromagnetic Design System (EMDS) comes with a list of impressive features. These key technological enablers demonstrate the advantages of full 3D EM design and verification:

• Arbitrarily shaped 3D passive structures for generalized EM analysis.
• Conductors, resistors, isotropic and anisotropic dielectrics, isotropic and anisotropic linear magnetic material modeling allow a wide range of application coverage.
• An unlimited number of ports, which enables simulating multi-I/O design applications such as packages.
• Electric and magnetic fields modeling, allowing visualization of EM fields in a design.
• Absorbing boundary condition (free space), allowing antenna modeling.
• Full-wave, EM-accuracy for first-pass design success.
• Multi-Mode impedance and propagation constants that overcome single-mode modeling limitations in many other EM modeling tools.
• Antenna parameters (gain, directivity, polarization, and so on), to allow better insight into antenna design.
• An EMDS/ADS link, providing an integrated approach to EM/Circuit design.

Application Areas

• Microstrip, stripline, CPW elements (filters, couplers, spiral inductors, via holes, air bridges, meander lines...)
• Multilayer structures
• Launches/transitions (coax-to-microstrip, microstrip-to-stripline)
• Ceramic filters
• Surface-mount components
• Waveguide filters
• Adapters/transitions
• Antennas
• Couplers
• Power splitters/combiners
• Connectors
• Mode converters
• Finline discontinuities

Visualization: Easy Display of Results

The visualization and animation capabilities in Agilent Electromagnetic Design System (EMDS) allow you to evaluate simulation results thoroughly.

To aid in analyzing your designs, EM field animation and dynamic rotation of structures can be performed simultaneously. Choose from shaded plots, contour lines, or vectors. 3D far-field plots illustrate beam shapes in both azimuth and elevation on a single plot.

The screen capture shows a tiled view of 3D E-field Cloud plot, far field (2D cut) polar plot, S-parameter plot and a 3D far field pattern.

Multiport S-Parameters

High-frequency design, whether at the component or the circuit level, requires knowledge of network S-parameters. Agilent Electromagnetic Design System (EMDS) computes S-parameters for single or multiport structures automatically.

Three types of S-parameters can be computed:

• 50-ohm S-parameters
• generalized S-parameters
• high-order S-parameters

Generalized S-parameters are normalized with respect to the characteristic impedances of the ports. Higher-order mode S-parameters are computed for a user-specified number of modes at each port, up to 20 modes per port.

Unique Features

ADS Layouts Linked to Agilent Electromagnetic Design System (EMDS)

Working toward a complete, end-to-end, solution from Agilent EEsof EDA, Agilent Electromagnetic Design System (EMDS) is in a path toward greater integration with Agilent Advanced Design System (ADS).

Layout geometries in ADS can be translated to Agilent Electromagnetic Design System (EMDS) for 3D EM simulation. Agilent Electromagnetic Design System (EMDS) solutions can then be reviewed or included in a larger ADS circuit.
