The Entry sheet, offsheet, and port functions of alicloud designer (reprinted)

1. Drawing Structure

There are two types of structural relationships in a drawing. One is a hierarchical drawing. The link is vertical, that is, a drawing of a certain level can only be associated with adjacent superiors or lower levels;

The other is flat drawing. The connection relationship is horizontal. Any two drawings can establish a signal connection.

2. Network Connection Mode

Alicloud designer provides the following network identifiers: Net label, port, and sheet entry ),

Power port, hidden pin, and off-sheet connector ).

The network ID is connected by name, and the signal can be transmitted if the name is the same. However, in addition to the "Port" and "sheet entry" identifiers,

Network IDs of other classes are not connected to each other even if their names are the same. For example, net label and port can only be connected

IDs of different classes with the same name are connected. "Automatic" is the default option, indicating that the system will detect the content of the project drawings to automatically adjust the range of network IDs.

The process of detection and automatic adjustment is as follows: if the sheet entry identifier is included in the schematic diagram, the range of the network identifier is adjusted to hierarchical.

3. Scope of "Port" and "net label"
The scope of the two network identifiers can be changed and changed. The method is to open the project \ project option \ option tag and select one of the four options (automatic, flat, hierarchical, and global) in the net identifier scope column.
"Automatic" is the default option, indicating that the system will detect the content of the project drawings to automatically adjust the range of network IDs. The process of detection and automatic adjustment is as follows: if the sheet entry identifier is included in the schematic diagram, the range of the network identifier is adjusted to hierarchical.

If the principal is not identified by the sheet entry. If the port ID is available, the network ID range is changed to flat. If there is neither the sheet entry identifier nor the port identifier in the schematic diagram, the scope of the net label is adjusted to global.
"Flat" indicates the flat drawing structure. In this case, the net label is still within the scope of a single drawing. The port function is extended to all drawings. as long as each drawing has the same port name, a signal can be transmitted.
"Hierarchical" indicates a hierarchical structure. In this case, the net label and port are used within a single drawing. Of course, the port can be connected to the sheet entry on the upper layer to transmit signals between drawings vertically.
"Global" is the most open connection method. In this case, the scope of net label and port is expanded to all drawings. As long as each drawing has the same port or the same net label, the signal transmission can occur.
