Can I resolve a spice netlist to determine what parts I need?
Since you tagged this with ltspice, if you check the menu for View &gt; Bill of Materials you'll see two options there. That will not list sources, though generating it on the schematic will make it to automatically update. If you want to do it manually, you can check the Generate Expanded Listing option in the Control Panel &gt; Operation, and check the error log after the simulation, where you'll see the whole netlist, flattened. It goes without saying that if you have encrypted models, they will not be expanded.
