CoventorWare Product Overview
CoventorWare is an integrated suite of design and simulation software that has the accuracy, capacity, and speed to address real-world MEMS designs. The suite has many MEMS-specific features for modeling and simulating a wide range of MEMS devices, including inertial sensors (accelerometers and gyros), microphones, resonators, and actuators. The software’s field solvers can model a wide range of MEMS-specific multi-physics, such as electrostatics, coupled electro-mechanics, piezoelectric, piezoresistive, and damping effects.
Whether exploring design concepts or performing detailed verification of device behavior, CoventorWare users benefit from our extensive MEMS simulation experience and modeling enhancements. CoventorWare is widely recognized within the MEMS industry as the best-in-class solution for multi-physics MEMS simulation, and sets the standard for MEMS simulation accuracy, capacity and speed.

To efficiently mesh the high-aspect-ratio structures typical of MEMS, it is imperative to use hexagonal (hex) elements rather than tetrahedral elements. CoventorWare includes a selection of meshing algorithms for generating hex-dominant meshes that are optimal for MEMS structures.
CoventorWare is widely recognized for accurately simulating electrostatic capacitance and force, along with non-linear, coupled electro-mechanics effects such as pull-in, lift-off and electrostatic spring softening. CoventorWare uses a hybrid finite-element/boundary-element (FEM/BEM) approach that avoids compromises to accuracy and efficiency.
CoventorWare provides a unique approach for simulating piezo-resistive (PZR) sensors, taking advantage of the dominance of the piezoresistive effect over shape change on sensor output. The stress field is precomputed using CoventorWare’s mechanical solver and mapped onto the geometry of the piezo sensor.
CoventorWare is an ideal environment for designing microbolometers, for which simulating the complete operation of the sensor requires analyzing multiple coupled physical domains, including thermal, mechanical, and electrical domains. It provides a fully coupled thermal-electrical procedure for analyzing this type of problem and employs finite elements that are well suited to modelling the thin films common to this type of device.
During MEMS fabrication, thermal cycling during deposition and etching can generate stress in deposited layers. CoventorWare enables MEMS designers to predict the 3D impact of residual stress by modeling isotropic, anisotropic and stress gradients in complex geometry, including conformal depositions.
CoventorWare couples piezoelectric and mechanical physics to accurately predict the frequency response of devices such as acoustic resonators, or devices that employ piezo physics for sensing and actuation such as energy harvesters.
