DCIR PCB Analysis
IR-drop describes the DC voltage that develops across a conductor as a result of its electrical resistance. This voltage is proportional to the current that flows through the conductor; for a given power plane, a larger current will result in a greater IR-drop voltage, and hence a lower voltage available at the load. Such voltage drops can cause device failure or safety breaches, when distributing power across a PCB.
Obtain voltage distribution of the power planes, indicating how much the local voltage drop is from the power plane rated voltage and whether it is acceptable.
Current Density plots give an engineer feedback on the location of current crowding and other bottlenecks. Very high current densities are a safety risk, as they are often coupled with high temperatures rises too.
Power Density plots gives an engineer feedback on the location of power crowding.
