Bring Massively Paralleled Processing Technology to Your Simulations

Bring Massively-Paralleled Processing Technology to Your Simulations

Address thermal heating challenges in chips, packages, and systems with complete electrothermal co-simulation for the full hierarchy of electronic systems from ICs to physical enclosures and end-to-end capabilities for in-design through to signoff.

The parallel processing technology within the Celsius Thermal Solver shortens simulation time significantly. Multi-threading and distributed processing are supported, enabling 10X faster simulation times than other solvers. The massively parallelized matrix solver can analyze 3D-ICs and complex 3D structures.

Harness Powerful and Hybrid Solver Technology

Innovative multiphysics technology addresses the challenge of multiple power profiles and increased heat dissipation by combining finite element analysis (FEA) for solid structures with computational fluid dynamics (CFD) for fluids, enabling complete system analysis in a single tool. The combination of FEA and CFD field solvers provides detailed analysis of the entire system, as well as detailed thermal model analysis of chip, package, and board designs.

Using the Celsius Thermal Solver, designers can import and analyze large package and PCB designs in full detail with no input simplification. Designers can also perform joule-heating, stress, and warpage analysis.
