Show Highlights:
- Tim Wang Lee Introduction
- Tim talks about Dr. Eric Bogatin as his mentor, the knowledge about simulation and signal integrity especially rule number nine
- A favorite phrase GIGO (garbage in garbage out) according to Tim is his way of understanding his intentions and asking questions before diving into a project
- Tim with Mike Russo, initiated simulation and measurement workflow seminars and webinars to help educate the importance of measurements and simulation to back it up
- What is a Virtual Prototype?
- Where to start with a system-level qualification in simulation?
- Tim explains what an EP Scan (Electrical Performance Scan) does
- Keysight is also now focusing on Power Integrity and Heidi Barnes is one of the leading experts in the Power Integrity ecosystem
- Next step for Keysight is to aid PCB designers in not only generating results but also fixing the issues

Making electromagnetic analysis accessible to anyone in the industry is what inspired Yuriy to create SIMBEOR® Electromagnetic Signal Simulator.
Yuriy Shlepnev is the founder and president of Simberian. In this episode, he will tell us about Simbeor simulation capabilities, and briefly educate us on rise times, signal integrity, and solving EMI. He will also show us the simulator in action and how it can be a lifesaver to PCB designers like you.
Tune in, enjoy and don't forget to check the additional resources below.

Show Highlights:
- uriy talks about his background in computational electromagnetics and how he got started working on simulations for PCBs and magnetic analysis
- Simulation capabilities accessible to lower data rates, Yuriy discusses rise times, signal integrity, and solving EMI simultaneously
- SIMBEOR® 2022 includes three simulation modes, and one of them is the Fast SI which uses more approximate models for pins, pads, and vias. It is a full wave, but not 3D. It allows simulations to run faster for more mass, included
- Simbeor SDK, a built-in software development kit in Altium Designer’s stackup manager. It uses the SFS solver for cross-sectional analysis, and that benefits Altium customers
- Yuriy shows us the 3D field solver in action
- Simulation of fiber weave effect on PCBs, is it possible?
- Coming soon in Simbeor SDK is the ability to build your own simulation tools
- Monte Carlo analysis is a perfect way to convert numeric model variations into a probability distribution
- What is the future of SIMBEOR® that designers can use to help them expedite important analyses for high-speed and RF designs?

Power Integrity and Simulations with Heidi Barnes
Wednesday Apr 20, 2022
Wednesday Apr 20, 2022
What a very insightful discussion with Heidi Barnes of Keysight. In this episode, we will discuss all things simulations and power integrity in detail. We will dive into EM simulations, capacitor placement, Z, Y, and S parameters correlation measurements, and more! You will learn a lot from this episode!
Altium 365: Where the World Designs Electronics
Show Highlights:
- Heidi’s background and her 30 years of experience in the PCB design Industry
- When she was only 17, she did an internship at Bill and Dave in Santa Rosa, which is now the Hewlett Packard (HP)
- She got into the solar industry and aerospace
- She is currently passionate about signal integrity and power integrity
- Heidi stresses the importance of simulation tools and mentions the need for having reasonable rules of thumb and have an understanding of what to expect before you jump into a simulation tool
- The Keysight’s PathWave ADS ( Advanced Design System) environment, what does it offer?
- Running an EM simulation and getting results through the pro environments– PiPro (power integrity pro), SiPro (signal integrity pro)
- On top of the DC analysis, it features a lot of great asymmetric tolerances analysis, current density, and thermal heat up effects analyses
- Heidi talks about capacitor placement–lowering the path inductance, allowing a higher frequency, and giving a broader power delivery from the printed circuit board.
- Capacitor Placement paper presented at DesignCon
- Addressing specific peaks that are exceeding the target impedance in a problematic PCB
- Heidi’s take on using ferrites
- Steve Sandler has a great video about How to Design for Power Integrity–how to select a regulator
- Z, Y, and S parameters–understanding simulation to measurement correlation
- Heidi wrote a paper on SI Journal website: Power Integrity Fundamentals: Impedance vs. Frequency
- She also tackles the “two-port shunt impedance measurement”
- Watch for another episode with Heidi Barnes, tackling subjects related to all things SI and especially getting into measurement issues, coming soon!
