Component pin names are indicated in the schematic, so each pin is easily identified. In addition, custom symbols that match the layout of the structure can be created to ensure that components are connected correctly (Figure 5). Figure 5: Custom schematic symbol for the select region of the PCB Conclusion The example presented in this application example showcases the powerful capabilities in theAWR Design Environment platform's PCB EM import wizard that help designers streamline the EM verification process for complex multi-layer PCBs. Designers can now select and import a PCB file and run a full EM simulation using a simple and automated process that significantly cuts simulation time without compromising accuracy. Acknowledgment Special thanks to Zuken for providing sample PCB files from which to develop this application example.
