[为什么] 比较从原理图生成的网表与转移到PCB布局的网表，以验证设计 [什么] 作为一个统一的环境，Altium 在幕后同步原理图数据与PCB布局，因此不需要交换中间网表的文本文件形式。 [如何] 要比较项目（原理图）与pcbdoc之间的数据，请调用项目 » 显示差异...，选择pcbdoc并点击确定。

At a Glance

Compare the netlist generated from schematics to that transferred to the PCB layout to verify the design. As a unified environment, Altium synchronizes schematic data with PCB layout behind the scenes, so there is no exchange of intermediate netlist in text file form. To compare the data between the project (schematics) and PcbDoc, invoke Project » Show Differences..., select PcbDoc, and click OK.

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.
