The AWR Design environment has several ways to be customized for your design technology. For integrated circuit processes, we have Process Design Kits (PDKs) for those process that define the technology including the models and layout cells. For PCB processes, the models can by any components the designer wants and so the technology setup is not as involved. What needs to be setup are the dielectric layers, vias, etc. The software ships with a tool to help you configure this process, select Tools > Create New Process from the menus. The dialog below will open to allow you setup your technology.
Please click on the Help button from this dialog or click on the Create New Process Documentation to see the help file.
