In this presentation, an EMC minded PCB design approach is presented, allowing designers to understand which EMC rules will apply to PCB projects and how EMC analysis capabilities can be utilized in the CAD flow to reduce the risk of EMC compliance failure once the board is manufactured.
In our webinar we will provide an introduction to the challenges of signal integrity and the underlying physical effects. This will provide the basis for practical tips to address the related challenges during PCB design.
ONTEC faced a difficult challenge: develop a multimedia broadcasting product while complying with a customer’s electromagnetic interference requirements, all within a tight development schedule. ONTEC used Zuken’s CR-8000 with Keysight’s ADS (including SiPro) to meet the requirements of the challenge
DDR5 is the latest generation of memory. In this joint webinar with Keysight Technologies, we’ll begin with pre-layout simulation, then transition to CR-8000. The design will then be verified by Electromagnetic (EM) simulation and system simulations in Keysight ADS, in order to build confidence in the final DDR5 design.

What IC designers do to help us route high-speed PCBs
In part 1 of this blog we took a back-to-basics approach and discussed line impedance and its effects in signal integrity. As every electrical conductor comprises capacitance, an inductance, and a frequency-dependent ohmic resistance, and with increasing frequencies, these electrical characteristics will influence and distort the signal.
Impedance and impedance control belong to the oldest and most often discussed topics in PCB design. They are especially important with the high-speed design when related to signal integrity. In this, the first of a two-part blog, we’ll go back to the basics of impedance/impedance control and consider what influences line impedance. In part two, we’ll set about controlling it.
Tips for when routing differential pairs - You can tell when something isn’t as clear as it should be. The same questions come up time and again. You ask three experts and get three different answers. Routing differential pairs can be like that. Why? Because “it depends” - on exactly what signals those pairs are carrying and what kind of PCB you’re creating.
