This documentation page references Altium NEXUS/NEXUS Client (part of the deployed NEXUS solution), which has been discontinued. All your PCB design, data management and collaboration needs can now be delivered by Altium Designer (with Altium Designer Enterprise Subscription) and a connected Altium 365 Workspace. Check out the FAQs page for more information.

Parent page: CAMtastic Commands

The following pre-packaged resource, derived from this base command, is available:

Applied Parameters: None


This command is used to compare the extracted netlist from the current document with the imported netlist (IPC-D-356 format) generated from the original PCB design document.


This command is accessed from the CAMtastic Editor by choosing the Tools » Netlist » Compare command from the main menus.


First ensure that the netlist for the current CAM document has been extracted and that you have imported the IPC-D-356 netlist.

After launching the command, the comparison will be carried out and a report, Netlist-Compare.rpt, generated and opened as the active document in the main design window. The report lists each of the nets that were found in the imported netlist but missing in the extracted netlist.


  1. Protel formatted netlists are not supported. The imported netlist must be in the standard IPC-D-356 format.
  2. If the IPC netlist has been imported correctly, you will see two layers added to the layers list in the CAMtastic panel: <fabrication_testpoint_report_for_DesignName>.ipc_t and <fabrication_testpoint_report_for_DesignName>.ipc_b, reflecting netlist information for the top and bottom signal layers. (A third layer, <fabrication_testpoint_report_for_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).
