SimLab offers a wide range of software products to aid engineers and designers in EMC simulation. Simlab's software, with it's frequency dependent analysis, utilizing both the PEEC (Partial Elements, Equivalent Circuit) and BEM methods, is far superior to comparable tools in the analysis of PCB's, cables, interconnects, and arbitrary structures ranging in sizes from large components, all the way down to IC design. The PEEC method excels in the analysis of these structures and their parasitic inductance, skin effects, dielectric losses, and resonance values. DC analysis is usually not possible with low frequency currents, but is easily handled with the SimLab tools. SimLab tools are also exceptional at handling no-ground, partial ground and imperfect ground planes, with shapes and dielectric constants (loss angles) fully variable to the user.

Greg McNeill and Matthias TroescherIntroduction to the SimLab Simulation Tools (1.9 MB)

All of the SimLab algorithms (including StatMod's PEEC, and the MoM) are continually being upgraded and modified with improved (GUI and algorithms) versions of the software released quarterly. The newly developed transmission line matrix (or transmission line method - TLM) algorithm was specifically designed for the detailed 2D analysis of exported PCB structures. SimLab publishes papers on the latest routines being implemented within the software and these are available to both users and potential users. Information on the theoretical background of some of SimLab's methods of computation can be found on the SimLab resources page or can be obtained directly from aEMCs. A prime example of SimLab "striving towards excellence" in engineering, physics, mathematics, and programming ingenuity is the ground plane modeller (split areas, no ground, with two full and an infinite number of partial area ground planes), developed years ago by the same people who have developed and are right now improving upon the already excellent TLM, PEEC, and MoM routines - SimLab!.

Cable Harness Simulation

CableMod™
The High Freq Cabling EMC Simulator

Developing complex electronic systems can be a great challenge for design engineers especially regarding electromagnetic compatibility aspects of the cables connecting the separate components.

The new standard in development is the 42V system, which will allow for smaller cables, but many more EMC problems will occur. The ongoing trend towards higher complexity, functionality and flexibility of harness systems together with the growing need to reduce their space consumption and weight typically result in non-ideal cable shielding. Additional measurement efforts would be necessary to cope with the problems arising when one has to investigate signal integrity and EMC behavior of such electronic interconnects. CableMod provides the user an efficient software tool for modeling and simulation of complex cable structures to overcome this bottleneck. CableMod includes powerful two-dimensional field solvers (Static2D - see below) for the determination of transmission line characteristics and a Spice-equivalent network simulator for calculating the currents and voltages in the excited conductor systems. Even though CableMod has it's own built-in CAD tool for design, CableMod also accepts Nastran file outputs from Catia or UniGraphics and can produce outputs for frequency/time domain analysis (I/V, s-parameter, distributed or lumped spice, distributed or lumped Saber, T model) and radiation calculations with SimLab's RadiaSim. The statistical bundling algorithm can be fixed, parameter, or Monte-Carlo, with variations in material dielectric losses, ohmic losses, cable, bundling, analysis, etc. CableMod can also handle no ground, non-ideal ground, or partial area ground planes, together with statistical material variations in conductivities.

PCBMod*
Total PCB EMC Simulator package utilizing both PEEC and BEM

PCBMod is an efficient software tool which can be employed in diverse stages concerning layout development of printed circuit boards and integrated circuits. The combination of ATHOS, Static2D/3D and StatMod integrated into one single program enables the user to analyse different types of circuit layouts from the analog and digital field. The functionality is not restricted by form or position of layout geometries.

RadiaSim™
SimLab's Radiation Simulator Utilizing the PEEC Method


RadiaSim is the powerful PEEC method radiation tool from SimLab. The tool enables the user to determine the Radiated Static as well as the Dynamic E- and H-field, intrinsic properties in defining emissions and susceptibility. This is done by defining Probe Points with the built-in CAD design tool (2D probes - point, line, circle, graph; 3D probes - plane, cube, sphere) in three-dimensional space (sizes of the probes and grounds can be manipulated) where the field is to be calculated. Antennae design can be circle, strip, or rectangle. Both monopole and dipole analysis options are included, with the ground (no ground or ideal ground) option manipulated by the user. The result can be viewed with the post-processors SLGraph and SLShow of SimLab. The result (voltage at the aerial base) can also be viewed with SLGraph.


StatMod™
High Freq 3D EMC Simulator Utilizing the PEEC Method

StatMod is a 3D EMC frequency domain simulation program that utilizes the PEEC numerical analysis method. StatMod also has it's own built-in CAD tool for PCB design investigations. The program StatMod was especially developed for layout planning of low frequency analog circuits. Parasitic effects from arbitrary placed area fills and ground planes (ideal, non-ideal, no-ground, partial area ground simulations, with 2 full ground planes and an infinite number of partial area ground planes) can be taken into consideration. The calculation and visualization of current and charge density distributions are only a few of its special capabilities. StatMod, combined with RadiaSim, can calculate power supply RF radiation, the most influential component for PCBs. 3D PEEC analysis of arbitrarily shaped structures extracted from PCBs (such as complex nets, vias, and their related structures), can be analysed for I/V Distribution, s-parameter, matrix, impedance, and partial SPICE outputs.


Static2D/3D™
2D and 3D EMC Simulators Utilizing the Boundary Element Method

Static2D/3D enables you to test any layout structure on printed circuit boards with digital and high frequency analog designs. Static2D/3D has it's own built-in CAD design tool for design investigations. Through Static2D/3D the circuit developer obtains diverse possibilities of usage in the field of modelling of transmission lines and discontinuities on PCB and IC designs, including ideal, non-ideal, no-ground, and partial area ground simulations. The program includes efficient two- and three- dimensional field solvers which calculate electrical parameters such as capacitances, inductances, resistances and wave impedances per unit length. Outputs include matrices (R,L,C,G) (Z,V,T), Spice lumped, Spice distributed, Saber lumped, Saber distributed, Eldo lossy wire, HSpice W Model, and T model.

ATHOS™
Pre-Processor Graphical Viewer and Layout Editor


High demands are made on planning and analyzing layout geometries and the verification of circuit functionality in industrial development and manufacture of printed circuit boards. Especially for the layout designer in the analog field the use of ATHOS offers an efficient enrichment in the design flow, because here an exact and quick examination of the circuit layout is made difficult by arbitrarily shaped copper areas arranged on the board. By integrating ATHOS into common PCB frameworks it is possible to fit in easily into an existing design environment.
