This analysis is run based on the IR drop analysis of the PCB layout. Thermal simulations are run with CST Studio Suite with the CHT (Conjugate Heat Transfer) Solver. Devices must comply with international EMC standards which regulate EM emissions of electrical and electronic systems in order to be sold.ĬST Studio Suite gives engineers simulation results relevant to all EMC aspects of a device such as the flow of currents across a circuit board. The results of the analysis are the self-impedances measured between pairs of power and ground pins.Įlectromagnetic Compatibility (EMC) is the ability of an electronic device to operate as designed in its environment without interfering with other devices. The goal of a power integrity analysis is to show the impedance (Figure 4) of the power distribution network as seen from component pins. (Figure 3) The transmission lines, signal source, and load can be analyzed regarding delay, over and undershoots as well as crosstalk. In high-speed devices, it is important to check the integrity of the signal paths. This tool quickly identifies traces and layers that violate the rules prior to running simulation studies. Rule checking allows the user to check the layout for violations with respect to standard EMC (Electromagnetic compatibility) and SI (Signal Integrity) layout rules. It has the capability to import PCB designs from the most popular EDA layout tools ( Figure 1 ) and incorporates several solver techniques to account for the most important analysis types. The CST PCB Studio is an electromagnetic simulation tool specifically for the simulation of PCBs. Simulation of these designs using CST Studio Suite (developed by SIMULIA ) in the development stage will identify problems that can be corrected prior to the start of manufacture. The PCB (printed circuit boards) within the electronic devices will create heat and need to be cooled. There are also Electromagnetic Compatibility (EMC) standards that must be met.
These circuits must work in conjunction with other electronic devices while keeping signal integrity (SI) and power integrity (PI). From household appliances, automobiles, and medical equipment to aircraft and mobile devices, electronic circuits are becoming very complex. Electronic devices are integrated into many product designs.
