Computer Simulation Technology (CST) has released the CST EMC Studio geared for electromagnetic compatibility (EMC) and electromagnetic interference (EMI) analysis. The simulation software contains a toolkit of proven solver technology for the study of EMC effects, with general purpose 3D modules for time and frequency domain simulation alongside more specialised solvers, stated the company.

EMC is an important consideration in product design across a wide range of industries. CST develops electromagnetic simulation software that help identify potential compliance issues before the actual prototype is built, and to analyse products that fail compliance testing. Engineers can study effects such as radiated or conducted emissions in consumer electronics devices, or susceptibility to electrostatic discharge, lightning strike and high-intensity radiated fields (HIRF).

The software includes the 3D transmission line matrix (TLM) 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. True transient EM/circuit helps analyse the effect of nonlinear circuitry on EMC performance.

Radiated and conducted emissions from PCBs can play a critical role in EMC performance of devices. For analysing printed electronics, the powerful import functionality and the EMC rule checker are of interest. EDA import formats supported include those used in Cadence Allegro, Mentor Graphics Xpedition, Zuken CR8000 and ODB++ databases. The EMC rule checker allows the detection of potential problems on PCBs that can be then analysed in 3D by the full wave solvers.
