Apsim FDTD
electromagnetic radiation is very important. The traditional electromagnetic
simulation tools are static or similar static TEM analysis. However,
frequency becomes higher , TEM method can not accurately calculate parasitic
electromagnetic field propagation ( such as secondary field , three games
etc.) , but these parasitic field just seriously affect circuit delay
crosstalk . Because the operating frequency increases ,
Product Features
• the use of "finite difference time domain" algorithm three-dimensional full-wave electromagnetic field simulator.
• accurate simulation of two, three games, accurate calculation of the diffusion field skin effect, dielectric leakage, the feedback current.
• the output at any position in the field as a function of time, current and voltage • accurate calculation method is very suitable for high frequency PCB board signal integrity simulation and EMI simulation.
• three-dimensional display simulation results, which will help to find, understand and remove the wrong source.
• Intuitive three-dimensional display of PCB EMI maps, spatial field distribution. • Output S parameter or in-circuit emulator with the circuit element;
• Output different functions transformation, for EMI, microwave and other analog applications, would further contribute to observed from the perspective of a function of frequency.
• to achieve accurate simulation of magnetic material and insulation material.
• particularly suitable for situations with Apsim FDTD addressed:
1. A self-coupling characteristics of clock line alignment;
2. EMC to more intractable problem, Apsim FDTD diagram of a field, enabling engineers accurately locate EMC problems;
3. In the PCB-containing three-dimensional structure, the interaction of the lead with a line IC, vias or ground planes such;
4. When the prediction of high-frequency, three-dimensional structure of vias, wire, IC packaging and so the return currents.
Features
• Maxmell solving equations in the time domain , using new algorithms that can handle big questions and get fine results.
• Use the new PML, not because of radiation on the border and affect accuracy.
• full-featured and intuitive simulation report.
• have a wider frequency range than any other a static two-dimensional , three-dimensional simulator, better accuracy.
• results are displayed graphically , easy to identify problems, spatial distribution is plotted as a function of a time- diagram.
Can be output at any time to field locations to the current and voltage function. This digital circuit design is ideal.
