31:31 Transmission Line Impedance Calculation With Altium Designer 13 min Webinars PCB Design Engineers PCB Design Engineers PCB Design Engineers Today’s PCBs contain many transmission lines. Combine this with increased clock frequencies and data rates and the result is a critical challenge to high-speed design. Neglecting these dynamics can undermine product development by compromising performance, power consumption, EMC/EMI compliance, and more - leading to delayed design cycles and opening gaps that can be exploited by your competition. Hone your high-speed design skills by joining us as we discuss the typical transmission lines encountered in today’s designs, the PCB variables that affect impedance, as well as how to create, calculate, and design transmission lines in Altium Designer. Learn how to maximize the built in SIMBEOR® engine by Simberian to craft impedance profiles and manage transmission lines in your designs. This Live Webinar recording covers the following: Current trends in electronics development PCB transmission line model and impedance calculations Transmission line with specified impedance in Altium Designer Don’t pass up on this opportunity to experience the industry’s best in class design experience!

Technical Documentation Preparing the Design for Signal Integrity Analysis In order to run a successful Signal Integrity analysis of the design and obtain accurate results, the following has to be performed before running the analysis. Although each net can be screened to provide net and impedance data, not all nets can be analyzed for signal integrity characteristics (voltage and timing). In order to screen successfully for all characteristics, a net must contain at…
