Protel formatted netlists are not supported. The imported netlist must be in the standard IPC-D-356 format.
If the IPC netlist has been imported correctly, you will see two layers added to the layers list in the CAMtastic panel: DesignName.ipc_t and DesignName.ipc_b, reflecting netlist information for the top and bottom signal layers. (A third layer, DesignName.ipc_in, will appear if you have internal signal layers in your PCB design. Unless you have blind and/or buried vias involving these layers, this third layer will be empty and can be left or deleted from the layers list).
If using the Design Explorer-based PCB Editor, the IPC netlist is created by generating a testpoint report and selecting IPC-D-356A as the output format. The individual options available for this format should be left disabled.
