Cadence Design Systems, Inc. introduced Cadence Celsius Thermal Solver, an electrical-thermal co-simulation solution for the full hierarchy of electronic systems from ICs to physical enclosures. Based on a production-proven, massively parallel architecture that delivers up to 10X faster performance than legacy solutions without sacrificing accuracy, the Celsius Thermal Solver seamlessly integrates with Cadence IC, package and PCB implementation platforms. This enables new system analysis and design insights and empowers electrical design teams to detect and mitigate thermal issues early in the design process—reducing electronic system development iterations.

As the electronics industry moves toward smaller, faster, smarter and more complex products with greater power density, time-consuming thermal transient analysis techniques must be deployed together with traditional steady-state analysis to address multiple power profiles and increased heat dissipation. Further complicating the process, traditional simulators require the electronics and enclosures being modeled to be substantially simplified, resulting in reduced accuracy.

The Celsius Thermal Solver uses multi-physics technology to address these challenges. By combining finite element analysis (FEA) for solid structures with computational fluid dynamics (CFD) for fluids, the Celsius Thermal Solver provides system analysis in one tool. When using the Celsius Thermal Solver in conjunction with the Clarity 3D Solver, Voltus IC Power Integrity and Sigrity technology for PCB and IC packaging, engineering teams can combine electrical and thermal analysis and simulate the flow of both electricity and heat for a more accurate system-level thermal simulation than legacy tools. In addition, the Celsius Thermal Solver performs both static (steady-state) and dynamic (transient) electrical-thermal co-simulations based on the actual flow of electrical power in advanced 3D structures, providing visibility into real-world system behavior.

By empowering electronics design teams to analyze thermal issues early and share ownership of thermal analysis, the Celsius Thermal Solver reduces design re-spins and enables new analysis and design insights not possible with legacy solutions. In addition, the Celsius Thermal Solver accurately simulates large systems with detailed granularity for any object of interest and is the first solution capable of modeling structures as small as the IC and its power distribution together with structures as large as the chassis.

The Celsius Thermal Solver supports Cadence’s Intelligent System Design strategy. It is built on matrix solver technology that is production proven in the recently announced Clarity 3D Solver and the Voltus IC Power Integrity Solution. Optimized for cloud environments, the Celsius Thermal Solver’s massively parallel architecture delivers up to 10X cycle time improvements compared to legacy solutions with high accuracy and unlimited scalability.
