The Right Time to Simulate is NOW! A journey in the new simulation technologies for RF Applications (Domenico Loricchio)

Engineers worldwide use Ansys HFSS to design high-frequency, high-speed electronics found in communications systems, radar systems, advanced driver assistance systems (ADAS), satellites, internet-of-things (IoT) products and other high-speed RF and digital devices. This workshop describes extension of the capability to more efficiently model complex RF devices.

11.30 am-12.30 pm

Application of Machine Learning to EMI problems in Aerospace and Defense Industry (Giancarlo Guida)

The number of parameters that play a significant role in the EMI performances of a practical system could be so large that conventional analysis and design methods do not cope with both EMC functional and certification challenges.

In this seminar, we present a new approach based on Machine Learning and Metamodels of Optimal Prognosis to explore efficiently the N-parameters Design of Experiment Space of a system to ascertain the impact on the EMI performances of each variable and to select the designs that better fit with the EMC requirements.

2.30 pm-3.30 pm

RFIC fully coupled Chip-Package co-extraction (Marco Occhiali)

In this workshop, the approach to perform fully coupled IC simulations will be presented, allowing to simulate with high accuracy the chip metallization and its package, capturing their coupling and interactions. The ever-increasing frequencies and data rates can cause severe electromagnetic issues. The heterogeneous multi-technology integration and high layout density require the accuracy of a 3D FEM solver, with the capability to combine layouts and perform co-extraction and co-simulation, both chip aware and package aware. The workshop will show how the Ansys HFSS 3D Layout platform allows to invoke best in class solvers to tackle this, without sacrificing ease of use: ECADXplorer offers GDSII preprocessing capabilities, making it easy to merge the chip on the package thanks to the hierarchical interface. The complex layout will be efficiently meshed with the groundbreaking HFSS Mesh Fusion technology.

4 pm-5 pm

Multiphysic Simulation Approach for 5G Filter Design (Alberto Di Maria)

Modern electronic devices are subjected to increasing power levels, higher frequencies, and sometime to a miniaturization process. All these aspects can lead to thermal and mechanical stress compromising safety, functionality, and reliability of our devices. The implementation of new technologies makes the use of predictive modeling techniques even more essential in designing electronic products.

In this workshop we illustrate an automated multiphysic approach dedicated to 5G filter design. This simulation workflow of thermo-electro-mechanical stress effects within filters allows engineers to prevent failures during the early stages of the design process and to reduce the time-to-market. All the steps of the electromagnetic simulation and the finite element analysis are highly automated and made easy to use for the designers.

DAY 2 (Wednesday 28th September 2022)

10 am-11 am

Survivability of RF Devices to Space Weather: Radiation hardening and Charging effects (Giancarlo Guida)

Survivability, an important requirement for every system that must survive in a critical environment, becomes vital when applied to the Space Industry.

The risks that can affect a satellite during its orbit can be manmade as in the case of impact with space debris, or natural as in the case of interactions with the space environment. On 23 October 2003, ADEOS-II had a power failure after an arc irreversibly damaged the solar array. Shortly after, the communications between the satellite and the ground stations ended with no further telemetry received. The mission ended with severe economic losses evaluated in 567 million USD.

Surface charging, internal charging and radiation hardening are some of the main electromagnetic threats for a spacecraft. In this lecture, we explore the benefits of using numerical modeling to implement a virtual testing environment to assess the survivability of satellites.

11:30 am-12:30 pm

Signal & Power Integrity and EMC analysis of Telecommunication PCBs (Flavio Calvano)

In this workshop, the typical Power and Signal integrity EMI/EMC issues on PCBs will be solved by a Full wave hybrid simulation approach coupled with the help of an advanced circuit simulator for the non-linear time transient analysis.

The PCB scattering parameter extraction provided by our full wave hybrid numerical code helps to identify issues on Power Delivery Network (PDN) and run a design of experiment genetic algorithm which can find the right decoupling capacitor strategy based on PDN noise and capacitor number minimization. Examples of this technique will be presented in this workshop. The circuit simulator, with the PCB scattering parameter to state-state space model conversion through advanced mathematical models, is used to build a full non-linear transient simulation to evaluate eye diagrams, voltage/currents transient diagrams and all the quantities useful for solving Signal Integrity issues, importing IBIS and Spice models for active devices in our environment. The time domain currents can be transformed in the frequency domain by a Fast Fourier Transform (FFT) and these can be analyzed as a direct output for conductive emission problems, connecting circuit models for the Linear Impedance Stabilization Network (LISN). Examples of signal integrity and EMI/EMC will be presented in real cases.

2.30 pm-3.30 pm

From Component to Mission: Simulation as must-have for aerospace & defense industry (HFSS & STK) (Domenico Loricchio)

Using STK, systems engineers develop workflows that seamlessly integrate the higher fidelity component models from its existing market-leading physics-based simulation tools like Ansys HFSS. The relationship between component and system-level modeling is significant for customers working in space applications and urban environments. This webinar will demonstrate a complete simulation workflow from the component-level modeling of an antenna to the system-level integration of the antenna onto a ship. Furthermore, an additional radar analysis is performed with STK with actual RCS data from a ballistic missile model with HFSS. Inhibition of this threat plays a key role in safeguarding human lives.

4 pm-5 pm

Leverage the Power of Automation with PyAEDT! A free fall in the new python library for Ansys Electronics Desktop (Alberto Di Maria)

Have you ever wanted to interact with Ansys Electronic Desktop with a modern, intuitive scripting language? Would you like to import geometries, set-up ports and create setups with single-line commands? And what about plotting results and edit the report appearance with intuitive and easy to understand commands, would that be cool? And if you want to get your result data and process them outside Electronic Desktop, now you can do that too.

This workshop will present the new PyAEDT Python library. PyAEDT interacts directly with the AEDT API to make scripting simpler for the end user. Its architecture can be reused for all AEDT 3D products (HFSS, Icepak, Maxwell 3D, and Q3D), 2D tools, and Ansys Mechanical. It also provides support for circuit tools like Nexxim and system simulation tools like Twin Builder. Finally, it provides scripting capabilities in Ansys layout tools like HFSS 3D Layout and EDB.

Electromagnetic Environmental Effects in Aerospace and Defense Industry (Giancarlo Guida)

The seminar aims to illustrate the role of E3 and EMC certification for current and future aerospace programs.

The need to reduce the economic and technological impact of experimental testing activities and the availability of increasingly powerful calculation tools and increasingly simple and fast calculation codes has made the numerical modeling of E3 phenomena an essential tool in the designer's working practice.

In particular, the issues related to the certification of aircraft with respect to the requirements for Radio Frequency Compatibility, Lightning and High Intensity Radio Frequency will be deepened and the issue of the interaction between satellite and the space environment in which it operates (Spacecraft Charging) will be addressed.

Human Exposure to 5G Radiation: Challenges and opportunities from numerical simulations (Domenico Loricchio)

Most 5G applications directly concern user equipment with wireless devices in close proximity to human beings, so assessment of human exposure is a crucial aspect for device manufacturers. Furthermore, a much higher density of infrastructures will force 5G base-stations to be closer to people than is common with current cellular infrastructure. In this workshop, we provide an overview of the main challenges related to human exposure assessment to 5G electromagnetic fields, highlighting the growing importance of numerical approaches and their benefits compared to measurement. In particular, the capabilities of state-of-the-art simulation solvers will be demonstrated by showing examples of SAR and power density evaluation on realistic test cases.
