TRANSLATE: KB: スキーマティックから生成されたネットリストとPCBレイアウトに転送されたネットリストを比較する

Solution Details

Altium synchronizes schematic data with the PCB layout behind the scenes as a unified environment, so there is no exchange of intermediate text files.  Since the ECO does a direct project to PCB compare, there is no native Altium netlist format:
Understanding Your PCB Netlist File

There is a command to export the netlist from schematics as a text file from Design » Netlist for Project» and from the PCB side, Design » Netlist » Create Netlist From Connected Copper', but unfortunately, the two do not follow the same format/syntax/order.

Instead, to compare the data between the project (schematics) and a PcbDoc contained directly, invoke Project » Show Differences..., select the PcbDoc, and click OK.
Finding Differences

You can also compare two different projects/documents by ticking Advanced Mode at the bottom of the dialog.
