In electronics design, a schematic bus connection is a method of representing multiple signals or connections in a single line in a schematic diagram. It is a convenient way to simplify the schematic and reduce clutter, while still conveying all the necessary information about the connections.

A schematic bus connection is typically represented by a single line with multiple branches, each branch representing a separate connection or signal. The branches are usually labeled with unique identifiers or names, which indicate the specific signals or connections that they represent.

A bus connection can be used to represent multiple signals that are related or connected in some way, such as the address lines in a microprocessor bus or the data lines in a serial communication protocol. By using a bus connection, the schematic can be simplified and made easier to read, without sacrificing the necessary information about the connections.

When designing a schematic with bus connections, it is important to ensure that the labels or names used for the branches of the bus are clear and unambiguous. This helps to avoid confusion or errors when interpreting the schematic and can make the design process more efficient and reliable.
