Polar Instruments Announces Additive Transmission Line Support for Si9000e
August 20, 2025 | Polar InstrumentsEstimated reading time: 1 minute
Transmission lines embedded into the PCB surface are a feature of UHDI constructions. The 2025 fall release of Polar's Si9000e PCB impedance & insertion loss transmission line field solver incorporates eight new single ended, differential and coplanar transmission line structures. With well in excess of 100 commonly used PCB transmission line structures the Si9000e allows designers, PCB technologists and PCB fabricators not only to solve for impedance or insertion loss, but also makes light work of exploring design space with a variety of tools for sensitivity analysis and the option to run Monte-Carlo simulations.
In addition to modeling loss and impedance, the Si9000e is capable of taking account of surface roughness effects and offers several industry standard methods for estimating the effects of surface profiles. Other useful features include a traffic signal warning for vias that require stub reduction by backdrilling, and the ability to estimate crosstalk. A further option extends crosstalk modelling to the coupling between differential pairs. Last but not least an alternative to 3d modeling of differential vias is included based on models provided by Bert Simonovich of Lamsim Enterprises.
Evaluation licenses are available and Si9000e may be commercially licensed from single user through to enterprise levels.
