Cary, N.C. and Pescara, Italy Coventor Inc. in partnership with MEM Research offers a new 2.5D and 3D electromagnetic (EM) technology for simulation of MEMS devices and other micro systems. Designated the EM3DS, Electromagnetic 3D Solver, the product offers a fast, customizable way for designers to calculate electromagnetic effects on micro systems. The simulation tools complement Coventor's existing suite of CoventorWare software tools for RF, microwave and MEMS devices or may be used as a standalone product.
The EM3DS tool uses a method-of-moments (MoM) platform instead of typical FEM-based simulations. The company says MoM is ideal for structures consisting of high aspect ratios where there is a large ratio between the smallest dimension and the largest dimension. By using the MoM technique, 2.5D and 3D simulations are produced about 50% to 300% faster than standard tools, where aspect ratio is an issue such as for planar structures, according to the company.
The software features pre- and post-processing capabilities, linear circuit analysis, network parameters, Smith charts, S-parameters and SPICE extractions. An object oriented integrated editor enables calculations by means of expression and frequency-defined materials. Geometry information may be imported from GDSII, AutoCAD DXF and BMP files.
"Coventor's EM3DS tool can move quickly between very detailed 3D simulations to 2.5D simulations with the click of the mouse, all in a standard windows environment," said Dave Cook, vice president of worldwide sales, in a statement. "This software is well suited for very complex structures integrating many dielectric substrates or stacks as well as thick metal and dielectric inclusions, commonly known as dielectric bricks."
Pricing for the EM3DS tool begins at $15,000 for an annual license.
