1 INTRODUCTION TO FDDEVS BUILDER ENVIRONMENT WITH EXAMPLE ATOMIC MODEL GENERATION AND VISUALIZATION Lahiru Ariyananda ACIMS UNIVERSITY OF ARIZONA

2 Outline This presentation will help you to setup a working FDDEVS Builder Workspace environment generate a DEVSJAVA Atomic model using a pre-defined FDDEVS example use SimView to Visualize it Note : Before you read through this guide, you need to have installed FDDEVS on an Eclipse IDE. If you have not installed FDDEVS, please see the relevant guides FDDEVS step by step installation guide for Eclipse IDE or Concise guide to installing FDDEVS on Eclipse IDE.

3 Step 1 : Setup a working examples folder in Eclipse Let us start by creating a working folder under FDDEVS project for the examples we will be doing. On Eclipse IDE under the FDDEVS project right click on the src folder go to NEW->Folder. give FDDEVSExamples as the folder name.

4 Step 1 cont

5 Step 1 cont Created FDDEVSExamples folder within Eclipse IDE

6 Step 2: Run FDDEVS Builder GUI from Eclipse To run FDDEVS Right click on MainFDDEVS.java (found under the src folder) in Eclipse Run As a Java Application.

7 Step 3 : Create a working folder for FDDEVS Builder environment On the FDDEVS Builder Workspace GUI go to File-> Create Folder

8 Step 3 cont Browse to the FDDEVSExamples folder under File Name type path

9 Note on FDDEVS folder path: 1. if you used the Concise guide to installing FDDEVS on Eclipse IDE to install FDDEVS the FDDEVSExamples folder will be under C:\installFDDEVSep\FDDEVS\src\FDDEVSExamples 2. if you used the FDDEVS step by step installation guide for Eclipse IDE to install FDDEVS the FDDEVSExamples folder will be under C:\eclipse\workspace\FDDEVS\src\FDDEVSExamples For this guide, we will be using option 1. ie C:\installFDDEVSep\FDDEVS\src\FDDEVSExamples

10 Important Note Once you do step 3 you will see 1. CurrentFDDEVSPath.txt file automatically created at location C:\installFDDEVSep\FDDEVS CurrentFDDEVSPath.txt file will contain the path C:\installFDDEVSep\FDDEVS\src\FDDEVSExamples\path 2. Models folder is automatically created at location C:\installFDDEVSep\FDDEVS\src\FDDEVSExamples\Models 3. Under Models folder Below subfolders withh be auto created i) doc ii) feedback iii) java iv)txt v)test vi)xml For this guide we will be looking at java, test and txt folders only

11 Step 3 cont Auto Generated folder structure under FDDEVSExamples as seen within Eclipse IDE

12 Step 4 : Import examples to the txt folder Within Eclipse IDE right click on the txt subfolder under (/FDDEVSExamples/Models) choose Import. Then choose File System and under General,click Next

13 Step 4 : Import examples to the txt folder Under Import File System From Directory browse to C:\installFDDEVSep\Examples as seen below. Check the Box next to Examples folder to select all.txt files within. Click Finish. You should see several.txt files imported now to the txt folder.

14 Step 4 : Import examples to the txt folder The above task can also be performed by Copying the contents of C:\installFDDEVSep\Examples Can use Ctrl+C To: C:\installFDDEVSep\FDDEVS\src\FDDEVSExamples\Models\txt folder Can use Ctrl+V

15 Step 5 : Open a predefined TennisPlayerA example. Now Go to FDDEVS Builder GUI choose File-> Open. Select TennisPlayerA.txt. Open.

16 Step 5 : Open a predefined TennisPlayerA example You should now see a similar screen as below. ( Don t worry about the text content for now)

17 Step 6 : Parse the TennisPlayerA example. On the FDDEVS Builder GUI click on the Show Parse button. If all is well, no errors will be shown as below.

18 Step 6 cont.. Note : The pre defined TennisPlayerA.txt model has been described using a Natural Language which we will look at in detail later. Show Parse function will scan through the text model and notify you if there are any syntax errors. In this particular case you should find no errors ( as the above figure) as the TennisPlayer model has been correctly defined before.

19 Step 7 : Generate a FDDEVS Atomic model from the TennisPlayerA.txt On the FDDEVS Builder GUI, click the Generate FDDEVS button.

20 Step 7 cont.. : Important Note Once Generate FDDEVS Button is clicked go to the Eclipse IDE click F5 to refresh. Make sure you do this step You should see an automatically generated TennisPlayerA.java under FDDEVSExamples\Models\Java folder TennisPlayerA.java is an auto generated DEVSJAVA Atomic model which was created using the text based TennisPlayerA.txt we opened previously

21 Step 7 cont.. Auto generated TennisPlayerA.java as send in Eclipse IDE

22 Step 8 : Visualize the TennisPlayerA Atomic model in SimView Go to the FDDEVS Builder GUI Choose Tools-> SimView

23 Step 8 cont A new window for SimView will open as below In SimView 1) Click Configure Button once to activate 2) under Select a Package Choose FDDEVSExamples.Model.java under Select a model choose TennisPlayerA

24 Step 8 cont Atomic Model of TennisPlayerA within SimView.

25 Step 8 cont You can experiment with it now. Above screenshot shows activity when step button is clicked. Real time factor is set to lowest and always show couplings checkbox is enabled.
