Coventor unifies MEMS design environment

May 19, 2017 // By Peter Clarke
CoventorMP 1.0 is a unified MEMS design platform that combines the established MEMS+ and ConventorWare offerings from Coventor Inc. (Cary, North Carolina).

CoventorWare is an integrated suite of design and simulation software that uses finite element analysis to design and simulate real-world MEMS designs. MEMS+ users assemble MEMS-specific building blocks drawn from a library, into a completed design. These MEMS+ designs provide simulation results up to 100 times faster than conventional finite element analysis tools.

CoventorMP 1.0, design platform supports the design of many types of MEMS, including gyroscopes, accelerometers, microphones, pressure sensors, scanning micro mirrors. It includes enhanced versions of CoventorWare (version 10.2) and MEMS+ (version 6.2), to allow free movement between the two aspects of design and create MEMS sensors and actuators and System-in-Package (SiP) components targeted at Internet of Things (IoT) devices.

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. 

Enhancements within MEMS+ include: lumped resistors and capacitor models useful for microphone noise modeling; speed up of large simulations by a factor of up to 3 and 50 percent less memory used; and extension of the Matlab scripting interface. Enhancements to CoventorWare include: the addition of the CoSolveEM provides better reporting of electrostatic pull-in results; FastPZE models thermal nonlinearity effects; and there is the capability to run CoventorWare Python scripts from a command line in a terminal window.
