For a decade now, Polar Instruments' Si8000m and CITS have been the de facto standard tools for controlled impedance PCB design and manufacturing test. The SB200 Stackup Design System added versatile and economical stackup features to the Si8000m impedance calculator. Now the Si9000e Transmission Line Design System shares the Si8000m easy-to-use interface, adding frequency dependent parameters such as loss and impedance components, RLGC and S-parameters. Free evaluation downloads are available from www.polarinstruments.com

The Si9000e field solving transmission line design software uses Polar's friendly interface featuring nearly 100 well-known pre-configured structures to provide easy computation of important transmission line design parameters such as frequency dependent losses, skin resistance, impedances, RLGC and S-parameters. For convenience and productivity the Si9000e connects to Polar's SB200 Stackup Design System. Parameters are displayed both in graphical form and tables, as well as output in various file formats.

Quickly and easily build a PCB stackup using the SB200's Wizard then modify your design with substitutions, additions, deletions layer by layer. Apply finishing to take account of the effects of pressing and curing. Add drill illustrations and controlled impedance traces on the various layers. Maintain reliable and accurate records of the overall stack and of individual layers. The design rule checker monitors your work to immediately point out any rule violations. Now add controlled impedance traces to the layers of your choice by linking to the Polar Si8000m or Si9000e.

Finally, provide clear, easy-to-read graphical printouts or data files in various formats to share with your customers or suppliers. Free evaluation software is available from www.polarinstruments.com

For a decade Polar have provided the PCB design and fabrication industry worldwide with the tools for designing the controlled impedance traces that reliably route high-frequency signals. The standard tool today, found throughout the design world and in PCB fabrication shops, is Polar's Si8000m. With or without its partner product, SB200 stackup design software, the Si8000m makes easy work of computing controlled impedance trace parameters for over 90 structural configurations. Whether it's a single, quick prediction of required trace profile using the Quick Solver interface or a detailed sensitivity analysis using our versatile Excel interface, the Si8000m produces reliable results quickly and economically. Get it right first time, every time.
