Calibration of a Numerical Simulation with Experimental Results Critical for Reliable Predictions

Every numerical method relies on the accurate choice of models, solver settings, and material parameters in order to be able to mimic real-world behavior. This also applies to Discrete Elements Method (DEM) simulations. You could use standard material properties, but adjusting those material interaction parameters using automated calibration methods is a key step for accurate simulations.

You could use standard material properties, but if you want to simulate reality, it is important to understand that the materials actually vary from site to site. Adjusting those material interaction parameters using automated calibration methods is a key step for accurate simulations. Even with basic materials, friction and restitution coefficients between particles and particles and boundaries have to be adjusted in order to accurately predict the bulk flow behavior. When extra forces come into play, such as adhesion forces, those additional parameters also need to be selected and properly specified. Continue reading

Creating Reliable SoC Designs Using N7 and InFO-WLP Technologies

According to Gartner, designing, testing and manufacturing 7nm FinFET-based system on a chip (SoC) requires massive resources: as much as $270 million and 500 man-years to bring the chip to market. Encapsulating such chips within a 2.5/3D package such as InFO-WLP improves power, performance and form factor while increasing the cost of design. To make a profit on that level of investment, the market for these chips tend to be high-end mobile and enterprise applications. To satisfy customer needs in these demanding markets, design teams have to deliver highly integrated devices that operate seamlessly and reliably for long periods of time. Additionally, you have to reduce the engineering time and cost, and ensure “first-time” working silicon. To do this you will need to move away from the traditional silo-based design flow to a chip-package-board co-simulation workflow and methodology. Continue reading
