Accurate modeling of PCB transmission line structures

Si8000m version 2.00 supports both single and multiple dielectric PCBs. The Polar Si8000m multiple dielectric controlled impedance design system is an all-new field solver based on the boundary element method (BEM). Si8000 uses Polar's easy to operate "Quicksolver" interface, but adds capability of modeling multiple dielectric layers. The Si8000m can also cater for the presence of resin rich areas between closely spaced differential pairs.

New for version 2.0 are optional modules that model 28 coplanar structures and 28 differential coplanar structures. Also new is enhanced goal seeking and additional standard models supporting increased dielectric layers.

Now Si8000 is available in fixed and floating seat editions, floating seat licensing being supported by FLEXlm™.

In addition to the accurate modeling of inner layer structures, the Si8000 supports enhanced models for surface traces, adding the ability to define a dielectric constant for soldermask and also define mask thickness between and adjacent to differential. This is especially beneficial if you need to predict how differing mask processes will affect finished impedance and propagation velocities.

For fabricators who need to predict and maximize yield, the Si8000 includes a tolerance seek facility which allows us to rapidly predict finished board impedance controlled yield based on the tolerance data of our raw material.

"Many prospective customers have approached us and asked for a product which is more affordable in the present marketplace", remarks Ken Taylor, Polar Instruments Signal Integrity Product Manager – "The Si8000m version 2.00 is offered with a totally new modular structure, making the system affordable for a whole spectrum of customers from small professional design houses, through to major OEMs".

The Si8000 field solving controlled impedance design system is available on a 3 or 12-month subscription basis or alternatively a full license. The 3-month subscription is priced to suit designers who need to use an industry standard field solver on a limited time basis. Twelve-month subscriptions include maintenance and support and are ideal for PCB shops that need a controlled impedance design system but prefer the flexibility of an annual license more suited to changing requirements.
