CAAPE User's Manual - ALSTOM Signaling Inc.

Introduction2.2.4. Using CAAPEUsing CAAPE involves the following major steps:1. Create a CAAPE project.2. Develop the applications: enter the “source” data that describes the configurationand operation of the VPI or CenTraCode II-s system. This data can either be enteredgraphically using editing tools provided by CAAPE, or textually using an external texteditor.3. Compile the applications: run the compilers that process the source data andgenerate the software which is then installed on the system’s boards. Compiling alsoproduces various report and other output files for manufacturing support,configuration control, and use by other Alstom utilities.4. Simulate the applications (optional): run the simulator program to simulate theoperation of the applications and verify that the application logic was writtencorrectly. Revise the application logic and recompile if errors are found. CAAPE’sGraphical Simulator uses information from the compilers to simulate the operation ofone or more applications. The user can lay out a track plan screen and link it to theapplication data to simulate the operation of field devices such as switches orsignals. The simulator also allows the user to view the state of individual variablesand equations as the applications run.5. Verify the Vital applications: use the Application Data Verifier (ADV) to analyze thecompiler output files and verify that their contents correspond to what the useroriginally entered. For example, the ADV proves that the compiler didn’t change themeaning of the application logic equations from what was intended.6. Program the boards using the compiler-generated output files. A download programis provided for those boards that support programming through a serial connection;other boards require physical programming and installation of EPROM chips.7. Perform revision control of the application data.P2512A, Rev. Oct/09 2–3 Alstom Signaling Inc.
