27 +When you start the KIELER executable, you probably need to set a (new) workspace location of your choice. (Click on the images to enlarge them).
28 +
29 +[[image:attach:kieler1.png]]
30 +
31 +If you selected a new workspace location, you will see a welcome screen like this:
32 +
33 +[[image:attach:kieler02.png]]
34 +
35 +Dismiss this "Welcome" tab. After that you'll be all set and KIELER should look like this:
36 +
37 +[[image:attach:kieler03.png]]
38 +
39 +In order to prepare modeling, we must create a project. Right-click in the Project Explorer to do so.
40 +
41 +[[image:attach:kieler04.png]]
42 +
43 +Select a General Project and click on next, then enter a project name, e.g. pldi14 and click on finish:
44 +
45 +[[image:attach:kieler05.png]][[image:attach:kieler06.png]]
46 +
47 +Now KIELER should look like this:
48 +
49 +[[image:attach:kieler07.png]]
50 +
51 +Now you can proceed in modeling an SCChart as explained below.
52 +
27 27  = Model an SCChart =

55 +Right-click on a project and create a (text) File:
30 30  
57 +[[image:attach:kieler08.png]]
58 +
59 +Name it abo.sct:
60 +
61 +[[image:attach:kieler09.png]]
62 +
63 +The textual SCCharts Xtext based editor (for *.sct files) will automatically be opened:
64 +
65 +[[image:attach:kieler10.png]]
66 +
67 +Now start modeling an SCChart. For example copy & paste the following sct code of abo, the hello world of SCCharts:
68 +
69 +{{code title="abo.sct"}}
70 +@VHLayout
71 +scchart ABO {
72 + input output bool A;
73 + input output bool B;
74 + output bool O1;
75 + output bool O2;
76 + region:
77 +
78 + initial state Init
79 + --> WaitAB immediate with / O1 = false; O2 = false;
80 + state WaitAB {
81 + region HandleA:
82 + initial state WaitA
83 + --> DoneA immediate with A / B = true; O1 = true;
84 + final state DoneA;
85 + region HandleB:
86 + initial state WaitB
87 + --> DoneB with B / O1 = true;
88 + final state DoneB;
89 + }
90 + >-> GotAB with / O1 = false; O2 = true;
91 + state GotAB;
92 +}
93 +{{/code}}
94 +
95 +As you save (Ctrl+S), KIELER will automatically draw the graphical SCChart diagram in a new KLigD view:
96 +
97 +[[image:attach:kieler11.png]]
98 +
99 +You may want to re-arrange views. Just drag the KLighD view to the right side:
100 +
101 +[[image:attach:kieler12.png]]
102 +
103 +You will now see how to generate a C tick function.
104 +
31 31  = Generate C Code =
32 32  
33 -xxx
107 +You can do several transformations on SCCharts (*.sct files). Just right click the file you want to transform in the project explorer and select the Transform SCChart sub menu. As abo is already a Core SCCart you do not need the core transformations. Click the All Normalize Transformations, this will do the Split Trigger and Effects and the Surface and Depth transformations together (in this order).
108 +
109 +[[image:attach:kieler13.png]]
110 +
111 +After performing a transformation the transformed SCChart will open (together with it's KLighD diagram visualization):
