Several common EMC simulation softwares

2 0 351

At present, there are many kinds of EMC simulation softwares in the world.

They are mainly used in high-frequency circuit board circuit applications, high-frequency filter circuit applications in all categories, high frequency antenna and waveguide applications, LTCC applications, transmission line applications (microstrip, stripline, coaxial cable, etc.), signal integrity applications and electromagnetic analysis. 

Most EDA software is based on modular applications, different modules to achieve different performance, the user can choose the module according to their own software configuration.

EMC simulation software provides a very effective high-frequency and high-frequency electromagnetic simulation applications, which combines high-frequency circuit modeling, simulation and optimization by one, with simulation instead of experiment, can quickly help engineers to complete high-frequency circuit EMC applications, to achieve signal integrity, reduce research and development costs, shorten the development cycle. 

Below a detailed overview of four typical EMC simulation applications.

(1) Ansoft High-Frequency and High-Speed Designers

This software is used by Ansoft Corporation, mainly for high frequency applications, signal integrity and electromagnetic applications of software products.

High frequency applications include:

(a) 3D Electromagnetic Field Finite Element Frequency HFSS;

(b) DESIGNER for RF, high frequency and communications applications;

(c) RF / Mixed Signal Ic and High Performance Signal Integrity Application Tool NXXlM.

Signal integrity application products include:

(a) Multilayer PCBs, integrated circuit packages and 3D application tools 3D EXTRACTOR

(b) Power and Signal Integrity Analysis Tools Siwave;

(c) TPA, a fast simulation analysis tool for high frequency Ic.

Electromagnetic applications and analysis tools include:

(a) 2D and 3D methods for electromagnetic and thermal analysis Maxwell 2D and 3D;

(b) System Modeling Tools SIMPLORER;

(c) Magnetic component application tool PEXPRT;

(d) Electronic Structure Rotation Performance Evaluation Tool RMXPRT.

(2) SimLab EMC Simulation Software

The software by the German company Simlab software applications, including circuit board MOd, CableMod, RaidaSim software products.

Board MOd is a powerful tool for simulating EMC / EMI, signal integrity, 2D and 3D simulations, introduction of board application data from major EDA databases, based on time domain and frequency domain analysis methods, detection of nodes on the voltage distribution, current distribution components, scattering parameters, impedance curves, radiation and so on.

CableMod is an interconnection analysis tool for modeling and modeling of complex cable structures and for 2D modeling. The main purpose is to analyze voltage distribution, current distribution and scattering parameters of nodes based on time domain and frequency domain analysis methods, Impedance curve, radiation and so on.

RaidaSim is a radiation calculation tool for circuit boards, wiring harnesses and equipment that can perform 2D and 3D simulations, introduce current density distributions, calculate near-field and far-field, 2D and 3D graphics results, and more.

The biggest drawback of this software is currently only work in UNIX and X-Window / Motif environment, has not yet released Window NT and Windows 2000 environment version.

(3) SONNET High Frequency Electromagnetic Software

Including Professional, Gold, Silver, sasic, LitePlus, Lite and other seven performance modules. EMC simulation software provides a very effective high-frequency and high-frequency electromagnetic simulation applications, which combines high-frequency circuit modeling, simulation and optimization by one, with simulation instead of experiment, can quickly help engineers to complete high-frequency circuit EMC applications to achieve signal integrity, reduce research and development costs, shorten the development cycle.

(4) FLO / EMC Design Class Electromagnetic Analysis Software for Electronics

Both individually and collectively for EMC applications and analysis of components, modules, systems, and antennas, 2D and 3D visualization of electromagnetic fields and currents based on time- Simulation, enclosure shielding effectiveness analysis, etc., can quickly model configuration, circuit and wire modeling, slit modeling, automatic generation of mesh, circuit modeling and shielding effectiveness analysis.
