EMI/EMC Simulation Software List（1）
Who know the following software? Which is the best? 1. Advanced Electromagnetics Description: GEMACS stands for the "General Electromagnetic Model for the Analysis of Complex Systems." It consists of a suite of electromagnetic modeling tools for method of moments (MOM), uniform theory of diffraction (UTD), and finite differences (FD). These three techniques can be used individually or combined into 3D hybrids to work more complex problems. The GEMACS package also contains numerous support utilities and a graphics interface called XGAUGE (X-window Graphical Aid for the Users of GEmacs). With XGAUGE a user can build a geometry model with GEMACS modeling elements, as well as view surface current, near-field, and far-field results with color-coded contours. The principal GEMACS sponsor is the U.S Army Research Laboratory and the U. S. Air Force Seek Eagle Office. 2. AnSoft Corporation Description: 2D electrostatic, magnetostatic, and low-frequency magnetic finite element analysis codes. Software: Maxwell 3D Description: 3D electrostatic, magnetostatic, and low-frequency magnetic finite element analysis codes. Software: Ansoft HFSS Description : 3D full-wave finite element code Software: Maxwell Eminence Description: electrostatic, magnetostatic and quasi-static field analysis and full-wave field simulation codes employing the finite element method and the boundary element method. Software: Microwave Explorer Description: 3D planar moment method for MMIC and hybrid circuit design. Software: Serenade Description: This is an integrated software suite for all high frequency circuit and system designs such as RF and microwave. It is applicable for the following levels of analysis: circuit, system, electromagnetic simulation, and the physical design. 3. Applied Simulation Technology San Jose, CA Phone: (408) 436-9070 FAX: (408) 436-9078 Software: ApsimRADIA Description: ApsimRADIA can simultaneously simulate radiated emission noise and conducted transmission line noise. It considers the impact of interconnect technology, cabling, packaging, and enclosure design on EMI. ApsimRADIA can predict both differential and common mode radiated emissions. Both types of EMI have a strong dependency on the physical design itself. Therefore accurate modeling tools to convert the physical entities into electrical properties are the key to successfully predicting the emitted radiation. ApsimRADIA uses a variety of field solvers to accomplish this. Software: ApsimRADIA-WB Description: ApsimRADIA-WB is designed to evaluate the impact of electrical and physical characteristics on EMI. ApsimRADIA-WB accurately predicts the radiated emissions from PCB, MCM, cables and subsystems. As a result, the user can investigate EMI issues from a system point of view as well. This avoids designs that work on a board basis but fail at the system level. ApsimRADIA-WB is a complete solution incorporating schematic capture, field solvers and EMI simulators in a fully integrated system. As the schematic is entered, the x,y,z coordinates of the physical interconnects are passed. Interconnect models can be simple impedance or delay lines or more complicated transmission lines as extracted from the field solver. The electrical models likewise, can be simple voltage or current sources, or more complicated behavioral IBIS or even Spice transistor level models. A 3D graphical playback display confirms the design. Once the design is entered, it is automatically simulated using ApsimRADIA and ApsimSPICE. The results can be viewed graphically or in a text, report, form and may be compared against an EMI standard of choice. Pass/fail assignments are then made. ApsimRADIA-WB provides insight into EMI issues resulting from physical placement, electrical specifications, interconnects and physical entities such as connectors. Design rules and conclusions leading to better designs can then be made at the earliest stage possible. The user can enter the physical interconnect locations and simulate their effects from a schematic diagram point of view. At the schematic level, changes to the electrical parts, physical entities and locations can easily be made without complicated CAD tools. Interactions of the physical locations of parts and electrical specifications of the interconnects can be studied for adverse effects. 4. Applied Wave Research, Inc. Redondo Beach, CA Phone: (310) 370-2496 FAX: (310) 793-6500 Software: EMSight Description: spectral-domain moment-method code for analyzing planar structures. 5. Bay Technology Aptos, CA Phone: (408) 688-8919 FAX: (408) 688-6435 Software: IE3D Description: 3D Planar, Full Wave, Method of Moments Electromagnetic Simulation and Optimization software. Circuit parameters are extracted from the solved current distribution and saved in formats compatible with time and frequency domain circuit simulators.
