Altium Designer changes the scope of the net label (Network label)

1. Version: Altium Designer 10

2, Reason: In the multi-schematic design, the different schematic diagram through the net label connection, and the ad default Net label (network label) scope is automatic, that is, when Sch has sheet Entry (sheet entry) or port (port), the net The label is scoped to a single sheet. In the design, the scope of the net label is modified because the port exists, but the net label is required to be scoped globally.

3. Steps:

PROJCT (Engineering), Options tab, Project option (Project parameters), select Global in the Net Identifier scope (network identifier range), and click OK to exit. As shown in.

4. Remark:

(1) Net Label Four range of functions:

"Automatic" is the default option, indicating that the system detects the contents of the project sheet, which automatically adjusts the scope of the network identity. The process of detection and automatic adjustment is as follows: If the schematic has sheet entry identification, the network identity is adjusted to hierarchical. If there is no sheet entry logo in the schematic diagram. However, with the port identity, the network identity is adjusted to flat. If there is no sheet entry logo in the schematic, and there is no port identifier, the net label scope is adjusted to global.
"Flat" represents a flat sheet structure, in which case the Net label is within a single sheet. The function of port extends to all drawings, and each drawing has the same port name, so it can transmit signal.
"Hierarchical" represents a hierarchical structure, in which case the Net Label,port is within a single sheet. Of course, the port can be connected to the upper sheet entry to pass the signal vertically between the drawings.
"Global" is the most open way to connect, in which case the Net Label, Port's scope extends to all drawings. Each drawing can be signaled as long as it has the same port or the same net Label.
