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.
PVsyst
PVsyst is a technical modeling tool designed to help you predict the energy yield of solar photovoltaic systems. You can import meteorological data from various sources and define specific system components like modules, inverters, and cabling to create a highly accurate digital twin of your project. The software handles everything from small residential setups to massive utility-scale power plants, providing you with the detailed reports needed for financial planning and technical validation.
You can perform complex shading analysis using a 3D CAD environment to see exactly how nearby objects impact your energy production. It allows you to account for thermal losses, horizon shading, and spectral effects to ensure your simulations match real-world performance. Whether you are an engineer designing a grid-connected system or a researcher studying stand-alone installations, you get the precision required for bankable solar energy assessments.
