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

 XFE option – provides crosshatch return path modelling for flex and flex-rigid PCBs

 Si Crosstalk option – Multi line and differential pair (lossless) crosstalk – models coupling between traces

 Si Excel Interface option – Microsoft Excel interface option for lossless calculations in Si8000m/Si9000e

 Projects option with Speedstack saves structure groups

Si9000e fast accurate PCB transmission line modeling.

With its fast, accurate, frequency-dependent transmission line modeling, the Si9000e Insertion Loss Field Solver is designed to model transmission line loss, impedance at given frequencies and extract full transmission line parameters over a wide range of popular PCB transmission lines (over 100 structures). Employing boundary element method field solving, the Si9000e extracts RLGC matrices and rapidly plots a range of transmission line information for the structure you are designing. Loss is graphed three ways with clear indication of dielectric, copper and total loss and includes Huray / Canonball /Gradient plus legacy Hammerstad, & Groisse methods for roughness modeling:

Speedstack Si – Stackup design for impedance & insertion loss controlled PCBs

Speedstack Si insertion loss controlled PCB stackup design tool is made for you if you are a designer, fabricator or PCB technologist who needs to manage PCB stackups with both impedance and insertion loss control. In addition to incorporating Polars proven insertion loss field solver capability, Speedstack Si allows rapid import and export of insertion loss projects into the Si9000e insertion loss field solver so you can analyse your stack up design in detail.

Speedstack PCB – PCB stackup / Impedance field solver package

Speedstack PCB stackup design tool is a packaged combination of the Si8000m field solving impedance calculator and the Speedstack professional layer PCB stackup design system. If you need both impedance calculation and layer stackup/build up documentation the Speedstack PCB offers a considerable saving over purchasing separate licenses.

For PCB fabricators, Speedstack PCB interfaces with the industry standard Polar Si8000m PCB Controlled Impedance Field Solver. It includes a link and license for Polar’s Si8000m, using the proven Polar Si8000m multiple dielectric boundary element field solver to provide the impedance data for the stack.
