Si9000e PCB controlled impedance frequency-dependent boundary element field solver

Si9000e — links with Speedstack as Speedstack Si

Si9000e — now adds inbuilt impedance graphing. 

With its fast, accurate, frequency-dependent transmission line modelling, the new Si9000e 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 90 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.

Si9000 graphs all losses - conductor, dielectric and insertion loss The Si9000 caters for both single and multiple dielectric builds, along with the ability to take into account solder mask performance. Mask coverage can be set adjacent, between and above traces. Many Polar customers request frequency-dependent impedance modelling, with particular reference to transmission line losses - the result is the Si9000e. The Si9000e is built on the same proven boundary element field solving platform as the PCB fabrication industry standard Si8000m. Increasing numbers of engineers are using the Si8000m as a rapid and accurate design tool for transmission line impedance - the Si9000e extends the output to extract full transmission line parameters.

Frequency-dependent calculations

Employing its Boundary Element Method field solving, the Si9000 extracts RLGC matrices and 2-Port (single-ended) or 4-Port (differential) S-Parameters and rapidly plots transmission line information for the structure under design. Graphing against frequency is provided for impedance magnitude, loss (conductor loss, dielectric loss and insertion loss), inductance, capacitance, resistance, conductance and skin depth. The Polar Si9000 runs within the Microsoft Windows environment and provides for simple transfer of table data to external programs such as spreadsheets or databases for subsequent analysis.

Extended substrate tables

The Si9000 frequency-dependent calculations can be refined using extended substrate data. Assign substrate values by frequency band to accommodate material from manufacturers who specify parameters that vary by frequency. Manufacturers may specify, for example, differing values of Er and loss tangent across a range of frequencies.

High layer-count builds

For those working with complex high layer-count builds the Si9000e also links to the Polar Speedstack PCB Stackup Design System and is available in the Speedstack Si package. Using the Speedstack Si allows you to keep all your stack design data in one convenient file - and you can draw library material from your fabricator or from base material suppliers in the Polar Material Partner program.

Designed to save you time compared with traditional methods, the Si9000e lets you choose graphically the structure you need to model and enter the geometric and material data and the range of frequencies under analysis. Select the graphs or table you need and the Si9000e solves for the results. Advanced users may also enter available data for Er and TanD versus frequency - the Si9000e will take these into account.
