What is the difference of Simbeor 3DML solver with existing 3D planar simulators?
There are some fundamental limitations in the other 3D planar tools. Extraction of parameters of lossy lines is usually available only for one-strip and symmetrical two-strip transmission lines only. There is no multimode analysis of lossy multiconductor lines in general. Loss effects in strips and planes are usually simulated with the equivalent surface impedance boundary conditions that is only a high-frequency approximation. In addition, these tools are usually optimized for narrow-band problems with non-causal models for dielectrics that leads to poor accuracy of the reduced-order models derived for analysis of wideband circuits. Note, that problem approximation typical for so called 3D planar of 2.5D solvers is available as a special simulation option in our Simbeor 3DML solver. It provides fast and accurate solutions for structures with large trace width to thickness ratio.
