Electrothermal Analysis of a PCB

Heat can degrade the performance and reliability of electronic devices.

Power dissipation of ICs and power losses across the board are key inputs for thermal analysis.

Electronics Cooling

Ansys’ industry leading computational fluid dynamics (CFD) solutions, along with chip-level thermal integrity simulation software, provide all you need to perform electronics cooling simulation and thermal analysis for chip-package, PCB and systems.

You can also conduct thermomechanical stress analysis and airflow analysis to select the ideal heat sink or fan solution. Our integrated workflow enables you to conduct design trade-offs, resulting in improved reliability and performance.

Thermal Reliability

Tight synergy with SIwave, Ansys Mechanical and Sherlock enables Icepak to accurately predict temperature rise using precise geometries and electrical inputs.

Icepak users can easily assemble automated workflows within the Ansys ecosystem to complete multiphysics analyses for electromigration, dielectric breakdown and multi-axial solder joint fatigue.

RF Systems and Circuits Analysis+

When combined with HFSS, circuits and RF systems simulation technologies create an end-to-end high-performance workflow for RF, EMI/EMC and other applications. It includes EMIT, a unique multi-fidelity approach for predicting RF system performance in complex RF environments with multiple sources of interference. EMIT also provides the diagnostic tools needed to quickly identify root-cause RFI issues and mitigate problems early in the design cycle.

Signal and Power Integrity Analysis+

When combined with HFSS, SI Circuits can be used for analyzing signal integrity, power integrity and EMI issues caused by shrinking timing and noise margins in PCBs, electronic packages, connectors and other complex electronic interconnects.

Signal and Power Integrity Analysis+

HFSS with SI Circuits can handle the complexity of modern interconnect design from die-to-die across ICs, packages, connectors and PCBs. By leveraging the HFSS advanced electromagnetic field simulation capability dynamically linked to powerful circuit and system simulation, engineers can understand the performance of high-speed electronic products long before building a prototype in hardware.
