Software Analyzes Electromagnetic Compatibility and Interference

Electromagnetic simulation solution provider Computer Simulation Technology AG (CST) says that its new CST EMC STUDIO software is designed specifically for analyzing electromagnetic compatibility (EMC) and electromagnetic interference (EMI) using 3D electromagnetic field simulation. With CST EMC STUDIO, says the company, engineers can study effects such as radiated or conducted emissions in consumer electronics devices as well as susceptibility to electrostatic discharge, lightning strike and high-intensity radiated fields (HIRF).

The developer describes CST EMC STUDIO as offering engineers a set of solver technologies for the study of emissions and susceptibility across a range of different components. The software comes with general-purpose 3D modules for time and frequency domain simulation as well as specialized solvers like a 3D transmission line matrix (TLM) method solver.

The TLM method solver, the company says, can help simplify numerical EMC analysis through its ability to use octree meshing to “significantly” reduce simulation time on extremely complex structures. The TLM method solver also supports analytic compact model representations of fine details. The software’s bidirectional cable/field simulation enables more realistic modeling of noise propagation and radiation over cables, and its true transient EM/circuit can help engineers analyze the effect of nonlinear circuitry on EMC performance.

CST EMC STUDIO also includes a cable harness solver, EDA (electronic design automation) and CAD import tools, circuit simulation tools and compact models for simulating vents and seams. The cable harness solver features bidirectional coupling between itself and the time domain solvers. This means that engineers can integrate cable harnesses into a complex 3D model and analyze them using bidirectional simulation.

When coupled with CST’s System Assembly and Modeling (SAM) environment for simplifying simulation project management, individual components can also be combined for a hybrid simulation. Through its dedicated EMC workflows, CST EMC STUDIO can be integrated into a wide range of product design processes, the company says.

For analyzing printed electronics, the CST EMC STUDIO PCB (printed circuit board) design rule checker reportedly helps engineers detect potential problems in imported PCB designs that can be then analyzed in 3D with the software’s full wave solvers. Supported EDA import formats include Cadence Allegro, Mentor Graphics Xpedition, Zuken CR8000 and ODB++ databases.

CST says that the solvers and tools in CST EMC STUDIO are drawn from the technologies used in its widely deployed CST STUDIO SUITE of electromagnetic simulation software as well as its CST BOARDCHECK program for EMC and signal integrity rule checking.

“In the last few years, we’ve seen increasing interest in our products from the world of EMC analysis,” said Bernhard Wagner, managing director, CST, in a press statement. “Through the development of simulation tools and specialized workflows specifically for this segment, numerical EMC analysis can be integrated earlier in the design process. With the introduction of CST EMC STUDIO, we further demonstrate our commitment to this field.”
