Ploar Si8000 PCB Controlled Impedance Field Solver
Si8000m PCB Controlled Impedance Field Solver – for single and multiple dielectric PCBs

The Si8000m is a boundary element method field solver that builds on the familiar easy to use user interface in earlier Polar impedance design systems. The Si8000m adds enhanced modelling to predict the finished impedance of multiple dielectric PCB builds and also takes into account the local variations in dielectric constant on close spaced differential structures. The Si8000m assumes negligible insertion loss in the transmission line; should you wish to model insertion loss the Si9000e adds extensive insertion loss modeling capabilities

The Si8000m links with Speedstack as Speedstack PCB.

Si8000m options

Si8000m – comprehensive modeling of over 100 structures
Surface coating is often overlooked when modelling and the Si8000m models the resist thickness adjacent to above and between surface traces. This offers a much more elegant solution which can be tailored to the particular resist application method in use on your boards. The new Si8000m also extracts even and common mode impedance. (Even mode impedance is defined as the characteristic impedance of one side of a transmission line pair when both lines are driven by a signal of equal magnitude and polarity). It is becoming increasingly necessary to control these characteristics on  high speed systems such as USB2.0 and LVDS.
Field solving Impedance design system

The Field Solvers in the Si8000m allow you accurately to graph impedance against various PCB parameters. The Si8000m Controlled Impedance Design System is a comprehensive controlled impedance design aid which can run stand alone as a Quicksolver, or the underlying engine can be applied directly though the optional Microsoft Excel user interface.
