Overview
Cadence Celsius
Cadence Celsius provides you with a unified platform to tackle the most difficult thermal challenges in modern electronic design. You can perform detailed thermal analysis for everything from individual integrated circuits to entire electronic enclosures. By combining finite element analysis with computational fluid dynamics, the software allows you to detect potential hotspots and mechanical stress issues early in your design cycle.
You can seamlessly integrate thermal analysis with your existing electrical power integrity workflows to see how heat affects performance in real-time. This approach helps you reduce the need for expensive physical prototypes and prevents late-stage design failures. It is specifically built for engineering teams working on high-performance computing, automotive electronics, and advanced mobile devices where heat management is critical for product longevity.
Diabatix ColdStream
ColdStream is a cloud-native platform that transforms how you approach thermal management and cooling challenges. Instead of manually iterating through designs, you define your boundary conditions and let the generative design engine create optimized cooling structures for you. It handles everything from liquid cooling and heat sinks to complex battery thermal management systems, ensuring your components stay within safe temperature limits while minimizing pressure drop and material use.
You can move from initial concept to a high-fidelity, manufacturable design in a fraction of the time required by traditional CFD methods. The platform is built for engineers in industries like automotive, aerospace, and electronics who need to solve extreme heat dissipation problems. By moving your thermal simulation to the cloud, you eliminate the need for expensive local hardware while gaining access to powerful optimization algorithms that explore design possibilities you might never have considered manually.
