Using CAAPE Graphics6.8. CREATING AND MANAGING GRAPHICAL SYSTEMSGraphical systems represent the user programming of a set of hardware, and are builtaround a graphical hardware component. You should create a hardware componentbefore you create the graphical system that uses it.6.8.1. Basic Concepts of Graphical SystemsThese concepts are explained in detail later.6.8.1.1. Component LinkingSince graphical systems represent the programming of a set of hardware, eachgraphical system is built around a hardware component. Additional components areassigned or “linked” to the boards in the hardware component to add logic, messageand protocol configuration to the system. For example, a Vital Serial messagecomponent might be linked to a Vital Serial board to define its communications; a logiccomponent might be linked to a processor board to define its application logic.See Adding Components to the System for more details.6.8.1.2. Make Files and Build NamesA graphical system is ultimately used to create the source text files which are compiledto create the application data. The conversion from graphics to text is called a “MakeFiles” operation. The various graphical subsystems must be converted to appropriatetext files for each application in the system. For example, hardware having a CPU IIboard and two CSEX3 boards is used to create the files for one Vital and two non-vitalapplications. The desired names of the source files to be created by a Make Files canbe set by using Build Names.For example, you might want the base names of the files for three applications to be“NorthCPU2”, “NorthCSX1” and “NorthCSX2” respectively. Assigning a Build Name of“NorthCPU2” to the CPU II board and Build Names of “NorthCSX1” and “NorthCSX2” tothe CSEX3 boards accomplishes this: when a Make Files is done, the resulting fileshave the desired names.See Make Files and Build for more details.P2512A, Rev.
