Yuriy Shlepnev of Simberian outlines the fundamental elements of DEA, examines the conditions for its accuracy, and highlights its growing importance in the future of interconnect design.

EM simulators that are optimized for PCB PDN simulations provide an increased level of automation to enable the basics of DC IR Drop, electrothermal, and AC impedance for early detection of design issues. In this article, Heidi Barnes, Steve Sandler, and Benjamin Dannan examine why the ability to optimize a PDN for Z_Target with PCB parasitics in the frequency domain and then export to an end-to-end PI Digital Twin simulation for validation in the time domain should be standard practice for the PI engineer.

Keysight Technologies, Inc. announced that the RFPro EM simulation software is now certified by Intel Foundry for design engineers targeting Intel 18A process technology.

Electromagnetic simulation tools will almost always give a result for any problem after pressing the run button. But is the result accurate? A methodology is introduced to establish the best practices for using the Ansys 2D Extractor and HFSS tools that include recommendations for the setup conditions, balancing accuracy, and computation time. With this methodology, an error in the absolute accuracy when solving for some electrical features can be achieved to better than 0.3%.

The China Telecommunication Technology Labs Terminal labs at the China Academy of Information and Communications Technology selected the R&S CMX500 OBT wireless communication tester to complement their DASY8 dosimetric and near-field evaluation system from SPEAG. 

Recently, Ansys released its HFSS Mesh Fusion product for simulation of complex EM systems. Signal Integrity Journal (SIJ) followed up with Dr. Matthew Commens, Principal Product Manager, HF at Ansys, Inc., to find out some more details.
