Product Description

E8925A Momentum Optimization takes EM simulation technology from simple analysis and verification to true design automation. This powerful geometry-based EM optimizer automatically refines the design until the best performance is achieved, all without designer intervention. The end result is better designs with greatly reduced refinement time.

How It Works

The optimization session consists of these general steps:

1. Creating a Momentum design for the nominal structure, with its substrate definition, metallization data, and port types and mesh parameters.
   
2. Defining geometric parameters as candidates for optimization. For each parameter, give a starting value, a perturbed value, and lower and upper bounds for the parameter.
   
3. Defining the optimization goals, such as a not-to-exceed dB value for the magnitude of S11, using the Design Specifications Editor.
   
4. Running the optimization. The optimizer runs without intervention, automatically varying and simulating the candidate variables to meet the specified goals.

Geometry Capture

Geometry Capture Offers Wide Optimization Choices

Setting up geometric parameters as candidate variables for optimization is easy with the geometry capture feature of Momentum Optimization. With geometry capture, the designer simply identifies a parameter to optimize. The software automatically creates a copy of the nominal design in a new layout window. The designer then edits the layout, and the software automatically translates the parameter value into the corresponding geometrical coordinates.

Comprehensive Set of Optimizers

Optimization Techniques Are Right For The Job

Momentum Optimization employs a comprehensive set of optimizers, including least squares, minimax, quasi-Newton, random, and simulated annealing algorithms. All of these optimization technologies have proven track records in engineering applications.

Interpolation for Speed and Efficiency

Momentum Optimization employs interpolation to significantly enhance its efficiency. The optimizer invokes Momentum for EM simulation only if the parameter value is moved across a user-specified interpolation interval.

For small changes in parameter values, interpolation is applied instead of EM simulation to obtain S-parameters. This can substantially reduce the amount of time it takes to run an optimization, without compromising the accuracy of the results.
