Board (dictionary item)
For automation interface information about a Board, see Board (automation interface).
Boards are the processing component within the system architecture. The detail of their composition is defined by a linked Board Type. A Board Type can be linked to many Boards. A Board Type describes:
• The Processors on the Board, their types and properties and the memory address for any on-board Memory.
• The Memory devices on the Board, their types and properties and their memory address.
• Any IO Devices on the Board, their types and properties and their memory address.
To change the characteristics of a Board you must change the linked Board Type.
You can create a Board through the context menu of a Package: right-click the Package, and select New > Proprietary > System Architecture > Board.
In addition, you can also create a Board by copying an existing Board. Modeler copies the Board's links. For more information, see Copying items.
When used on a System Architecture Diagram, a Board's notation is as follows:
If a Board has two or more instances, the following notation is used.
In the Modeler panes, a short-cut symbol on the Board's icon indicates that the item is a stub. For more information, see Stubs.
To specify that a Board runs the software of a Package, link the Board to the Package: From the Board's Property Pages, click the Items tab, select Packages in the Show Associated list, click the Link button, and then select the Package.
To see how a Board is defined using Board Type, Processor, Processor Type, Memory, Memory Type, Board IO Device and Board IO Device Type items, see .

Dependency - The Dependency is owned jointly by the Board and the other associated item. The access permissions you have to a Dependency are determined by the access permissions of the dependent item.
Drop - The Drop is owned jointly by the Board and the associated Multidrop Bus. The access permissions you have to a Drop are determined by the access permissions you have to the source item.
Point-to-point Connection - The Point-to-point Connection is owned jointly by the Board and the associated item. The access permissions you have to a Point to Point Connection are determined by the access permissions you have to the source item. Note that the Board does not own the Point-to-point Connections that are linked to the Board's Board IO Device.
