CoventorWare 2012 Software increases 3D simulation capacity and accuracy to ease verification of complex MEMS devices
Latest release focuses on solving the bigger, more complex challenges of verifying the next-generation of integrated MEMS devices with more accuracy and greater efficiency
At the IEEE MEMS 2012 Conference today, Coventor®, Inc., the leading supplier of software for developing micro-electromechanical systems (MEMS), introduced the 2012 release of its best-in-class CoventorWare® solution for MEMS design verification and optimization. CoventorWare 2012 capitalizes on increased computing power and software algorithm advancements to enable more complete and accurate verification of state-of-the-art MEMS designs.

Simulate Complex Designs More Accurately
CoventorWare is an integral part of Coventor’s MEMS design automation platform for rapid evaluation of design concepts, optimization and MEMS+IC integration. It is used for verification and optimization of device designs starting from layout through analysis of MEMS-specific multi-physics, such as coupled electro-mechanics, gas damping, anchor losses, thermo-elastic damping (TED), and manufacturing-induced stress gradients. CoventorWare 2012 is focused on solving the big verification challenges faced by MEMS designers developing the next generation of MEMS devices.
“CoventorWare 2012 provides an entirely new level of simulation capacity and accuracy. It enables us to rapidly examine all aspects of our high-performance resonators in simulation and predict the Q factor due to thermo-elastic damping within five percent of measurement. As a result, we are able to further reduce the size of our quartz crystal and maintain the high Q necessary to interface with standard ICs, significantly extending our technology advantage in this highly competitive market,” commented Silvio Dalla Piazza, vice president of Research & Development at Micro Crystal AG, a subsidiary of The Swatch Group Inc. Switzerland.
With the increased memory capacity of 64-bit computing, CoventorWare users can now simulate more complex designs and obtain higher accuracy with finer meshes. Full 64-bit support has been implemented across the entire Coventor software suite, including the solid modeler, preprocessor and meshing, visualizer and all MEMS solvers. A single installation provides both 32- and 64-bit support that automatically runs in 64-bit mode on 64-bit operating systems.
The CoventorWare 2012 hex-dominant extrusion meshing option also increases simulation capacity and is ideal for typical MEMS structures, which are made up of high aspect ratio (fairly thin), stacked layers of materials perforated with release etch hole patterns. It automatically generates meshes that have uniform density and quality, unlike competing solutions that generate very inefficient tetrahedryl meshes or require extensive user involvement to produce an efficient hex-only mesh. This new capability reduces the number of mesh elements required for typical MEMS devices by as much as 20 to 40 percent, making it possible to simulate entire multi-axis inertial MEMS sensors with 100s of electrostatic comb fingers.
Automate Simulation Tasks
The all-new Python scripting interface for the CoventorWare 2012 field solvers enables users to automate repetitive tasks and perform more sophisticated types of analysis, such as multi-dimensional parametric studies. With CoventorWare 2012, users can set up simulations via the graphical user interface and then automatically generate Python scripts, eliminating the need to write scripts from scratch. Additionally, they can combine automatically generated scripts to automate series of simulations and post-processing tasks, while also benefiting from full access to the extensive numerical computation and plotting capabilities of the widely used Python language.
Python scripts can be executed from the new CoventorWare console, which is a unified graphical interface for accessing all CoventorWare functionality. The console provides access to all simulation management functions in a single window while remaining compatible with the classic user interface, ensuring that both new and existing users can quickly become productive. The console also simplifies simulation setup for the enhanced versions of the MemElectro, MemMech, CoSolveEM, HamonicEM and DampingMM solvers provided with the CoventorWare 2012 software release.
The CoventorWare 2012 software is shipping today. For more information about CoventorWare solutions, visit: http://www.coventor.com/products/coventorware/.
