CST EMC STUDIO, a product for electromagnetic compatibility (EMC) and electromagnetic interference (EMI) analysis, has been introduced by Computer Simulation Technology. Engineers can use the tool to study effects such as radiated or conducted emissions in consumer electronics devices, or susceptibility to ESD, lightning strike and high-intensity radiated fields.

Electromagnetic simulation solutions help identify potential compliance issues before the actual prototype is built and analyse products that fail compliance testing. CST EMC STUDIO includes proven solver technology for the study of EMC effects, with general purpose 3D modules for time and frequency domain simulation.

Specialised solvers are also provided, such as the 3D transmission line matrix method solver, which implements technology that simplifies numerical EMC analysis, such as compact models and octree meshing. The bidirectional cable/field simulation enables more realistic modeling of noise propagation and radiation over cables, while the true transient EM/circuit helps analyse the effect of nonlinear circuitry on EMC performance.

The EMC performance of a device can be affected by radiated and conducted emissions from PCBs. The powerful import functionality and the EMC rule checker, which allows the detection of potential problems that can be analysed in 3D by the full wave solvers, help when analysing printed electronics.

Dr. Bernhard Wagner, Managing Director, Computer Simulation Technology, comments: “In the last few years, we’ve seen increasing interest in our products from the world of EMC analysis. Through the development of simulation tools and specialised workflows specifically for this segment, numerical EMC analysis can be integrated earlier in the design process. With the introduction of CST EMC STUDIO, we further demonstrate our commitment to this field.”

Supporting EDA import formats including those used in Cadence Allegro, Mentor Graphics Xpedition, Zuken CR8000 and ODB++ databases, CST EMC STUDIO is available now.
