Overview: Our Products for MEMS Development
For over two decades, Coventor has supplied world-leading MEMS companies and R&D organizations with simulation tools that accurately predict the complex, multi-physics behavior of MEMS devices. Our on-going focus has resulted in MEMS-specific capabilities and simulation expertise that helps our customers significantly reduce time to market.
New, Integrated Design Methodology
Coventor offers integrated products for MEMS design: CoventorMP®, MEMS+® and CoventorWare®. These software tools are ideal for MEMS devices that employ mechanical, electrostatic, piezo-electric, piezo-resistive, or thermal effects for sensing or actuation. CoventorMP is a unified design platform for MEMS design, that allows transfer of MEMS device models between the MEMS+ and CoventorWare design software products. MEMS+ and CoventorWare work seamlessly together in the CoventorMP framework. They provide a design platform that enables MEMS designers to simulate critical end-product performance specs such as sensitivity, linearity, frequency response, signal-to-noise ratio, temperature stability or actuation time. Both products are useful in all phases of a typical MEMS development program.
The CoventorMP platform contains both the MEMS+ and CoventorWare software products. Many customers purchase CoventorMP to take advantage of the complementary strengths of MEMS+ and CoventorWare.
CoventorMP Software Features
CoventorMP combines the complementary strengths of Coventor’s industry-leading software tools for MEMS design, CoventorWare® and MEMS+®, into a single powerful environment for MEMS design automation. The new platform provides a cohesive environment where designs can be entered once and used to create conventional finite element models (CoventorWare) and compact finite element models (MEMS+).
The CoventorMP platform provides a unified environment for MEMS design, starting from fully parametric design entry to the production of functional models that can be simulated at all levels of abstraction. In essence, design data in CoventorMP will serve as a single “golden master” for all types of modeling, eliminating the need for time consuming and error-prone manual transfer between different modeling environments. MEMS device models created in CoventorMP can be simulated with built-in solvers or automatically transferred into MATLAB®, the Simulink® system modeling environment, the Cadence Virtuoso® circuit modeling environment, and SPICE simulators that support Verilog-A.
|Rapid design exploration and optimization. Models are assembled from a library of parametric, high-order finite elements and can simulate up to 100X faster than conventional FEA, enabling
|Detailed device analysis with a suite of FEM/BEM solvers. The 2D-to-3D model builder, automatic meshing and field solvers are optimized for MEMS structures and multi-physics, addressing most types of MEMS:
Developing MEMS Processes and Structures for High Yield
Unlike CMOS processes, MEMS processes are highly customized to a particular class of devices making it essential for all stakeholders in a MEMS development project to fully understand and account for processing effects. To reduce prototyping and improve yield, Coventor offers two separate products, CoventorMP® and SEMulator3D®, that make it easy to build 3D structural models from 2D design data (layout). While CoventorMP produces models that are ideal for field solvers, SEMulator3D creates models that include realistic processing effects such as rounding of conformal deposits, undesirable voids, and incomplete release etches. SEMulator3D models are used to predict, diagnose, and resolve complex processing issues. Most importantly, SEMulator3D models are used to verify MEMS designs prior to tape-out. SEMulator3D is now part of the standard verification flow at well established MEMS fabs and independent foundries.
