Detailed Description

Each graphical item can have a SCH_CONNECTION describing its logical connection (to a bus or net).

These are generated when netlisting, or when editing operations that can change the netlist are performed.

In hierarchical schematics, a single SCH_ITEM object can refer to multiple distinct parts of a design (in the case of a sub-sheet that is instanced more than once in a higher level sheet). Because of this, a single item may contain more than one SCH_CONNECTION – each is specific to a sheet.

Components contain connections for each of their pins (and for each sheet they exist on) but don't use their own connection object.

Constructor & Destructor Documentation

◆ SCH_CONNECTION() [1/2]

SCH_CONNECTION::SCH_CONNECTION ( SCH_ITEM aParent = nullptr,
SCH_SHEET_PATH  aPath = SCH_SHEET_PATH() 
)

Buses can be defined in multiple ways.

A bus vector consists of a prefix and a numeric range of suffixes:

BUS_NAME[M..N]

For example, the bus A[3..0] will contain nets A3, A2, A1, and A0. The BUS_NAME is required. M and N must be integers but do not need to be in any particular order – A[0..3] produces the same result.

Like net names, bus names cannot contain whitespace.

A bus group is just a grouping of signals, separated by spaces, some of which may be bus vectors. Bus groups can have names, but do not need to.

MEMORY{A[15..0] D[7..0] RW CE OE}

In named bus groups, the net names are expanded as <BUS_NAME>.<NET_NAME> In the above example, the nets would be named like MEMORY.A15, MEMORY.D0, etc.

{USB_DP USB_DN}

In the above example, the bus is unnamed and so the underlying net names are just USB_DP and USB_DN.
