Si9000e PCB Transmission Line Field Solver The Si9000e PCB controlled impedance frequency-dependent boundary element field solver combines powerful impedance calculation over a wide range of structures and unprecedented ease of use:
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.
With a range of license packages to suit your budget |

Powerful S-parameter graphing With the Si9000 PCB Transmission Line Field Solver you can view the full range of 2 and 4-port S-parameters in a single chart window. Click on the links below to display the full range of 4-port S-parameters data series, S11 — S44. Mixed mode S-parameters The Si9000 provides a comprehensive range of data presentation in both tabular and chart form with the option of single-ended and mixed-mode S-parameters.
The differential S-parameters, SDD11, for an edge-coupled surface microstrip are shown below.
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. Si9000 graphs Impedance magnitude with frequency Conductance v frequency Skin depth v frequency Extended substrate tablesThe 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. Extended substrate data tables Frequency modelling down to 1KHz For frequency dependent calculations the Si9000e calculation engine supports lower frequencies down to 1KHz.

Via stub check The Si9000 incorporates a Via Stub check that provides a simple color coded go/no go check on the potential for signal distortion 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 Si9000 Via Stub Check supports three modes:

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.
