Polar’s signal integrity solutions equip the industry from pre-layout design to post-fabrication test, offering simulation, documentation, design and test tools for speedy, accurate and cost-effective results. Design transmission lines with impedance field solvers and calculate insertion loss now including Groisse and Huray copper roughness models. Design rigid or flex, high-layer PCB stackups with multiple impedance traces and document them transparently for the fabricator. Then export stackup data to PCB layout tools and generate Gerber files for impedance test coupons. (less)
