Polar Instruments Si9000e  v24.10
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:

    Links with Speedstack as Speedstack Si

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

    Si Projects option with Speedstack saves structure groups

    Roughness modeling – Cannonball-Huray / Gradient / Hammerstad / Groisse

    Roughness input data Rz (Canonball-Huray) / RMS (Rq) Gradient

    Inbuilt impedance graphing

    Graphs conductor, dielectric and insertion loss

    At-a-glance comprehensive S-parameter charting – magnitude, phase and Smith charts

    Single-ended and Mixed-mode S-parameters charting and data tables

    User defined S-parameter source and termination impedance

    Frequency dependent modeling down to 1KHz

    Differential via calculation

    Go / no go Via Stub Check

Si9000e graphs all losses – conductor, dielectric and insertion loss. The Si9000e caters for both single and multiple dielectric builds and comes 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.

Differential Via Calculation / Via Stub Check

The Si9000 incorporates:

Differential Via Calculation, providing a quick and accurate circuit model for modelling differential through-hole vias.

Via Stub Check that provides the signal distortion effect of a via stub. The effects of the stub will increase as the stub length and Er increase and the signal rise time reduces. The Si9000e Via Stub Check supports three modes:

    Stub Length, Effective Er and Bit Rate Frequency

    Stub Length, Effective Er and Single Frequency

    Stub Length, Effective Er and Rise Time
