Removing The Accuracy And Time Tradeoff In EM Simulation


For years, electromagnetic simulation forced engineers to choose between accuracy and turnaround time. As simulation frequencies climbed beyond 60 GHz and designs became more complex, engineers could no longer avoid mesh refinement. Higher fidelity required more mesh elements in regions of high field strength. More elements produced larger sparse matrices. Larger matrices extended solve time... » read more

Sparse Finite Element Problems on Neuromorphic HW (Sandia National Lab)


A new technical paper titled "Solving sparse finite element problems on neuromorphic hardware" was published by researchers at Sandia National Lab. Abstract "The finite element method (FEM) is one of the most important and ubiquitous numerical methods for solving partial differential equations (PDEs) on computers for scientific and engineering discovery. Applying the FEM to larger and mor... » read more

Controlling Warpage In Advanced Packages


Warpage is becoming a serious concern in advanced packaging, where a heterogeneous mix of materials can cause uneven stress points during assembly and packaging, and under real workloads in the field. Warpage plays a critical role in determining whether an advanced package can be assembled successfully and meet long-term reliability targets. New advances, such as molding compounds with impro... » read more

The Computational Electromagnetics Simulation Challenge Of 3D-IC


By Kelly Damalou and Matt Commens Innovation in semiconductor design today is energized primarily by AI/ML, data centers, autonomous and electric vehicles, 5G/6G, and IoT. Recently developed 2.5 and 3D-IC silicon-based packaging technologies have advanced the state of the art beyond SoC technologies which first united digital, analog, and memory functions on a single chip in the '90s. These ... » read more
