Using CAAPE Graphics6. SECTION 6 – USING CAAPE GRAPHICS6.1. GRAPHICAL WORK FLOWGraphical operation allows the user to configure a system by combining reusablecomponents that are edited using a graphical approach. This approach has theadvantage of prompting for needed data instead of forcing the user to remember or lookup a large number of text records and their formats.The graphical process for creating a new system involves these steps:1. Creating or importing the necessary graphical components. Graphical componentsare the graphical “building blocks” used to enter the application data.2. Editing the components. Various graphical editing tools are provided by CAAPE.3. Creating or importing a graphical system. A graphical system represents a VPI, WIU,iVPI or CenTraCode II-s hardware system and contains the application programmingneeded to make it run at the customer location.4. Linking the components into the system. This process combines the graphicalbuilding blocks to describe the system.5. Performing a Make Files operation to create the textual application source data filesfor the compiler to process.6. Compiling the source files to produce the output and report data files.7. Optionally performing simulation to check whether the application logic is correct.8. Performing Application Data Verification to verify that the Vital application datagenerated by the compiler accurately reflects what the user entered.9. Programming the EPROM memory devices on the boards to install the applicationand system software.Steps 1 through 4 is can be performed in any order. New components can be created atany point, and editing does not have to be complete before a component can be linkedinto a system.Changing an existing system involves all the above steps except for 3, since thegraphical system is already created: existing components are edited, new ones arecreated and linked into the system, a new Make Files is performed, etc.P2512A, Rev.
