SCT is a textual description language for SCCharts. Due to space limitations SCT is not documented in the PLDI paper, but examples can be found here. Also the code completion functionality of the textual editor for SCT is very helpful. It can be invoked by pressing <Ctrl> + <Space>. It will list all syntactically possible input according to the SCT/SCCharts meta model.

Now start modeling an SCChart. For example copy & paste the following sct code of ABO, the hello world of SCCharts (you can find more example models here, a description of the textual SCCharts syntax (SCT) can be found here):

@VHLayout
scchart ABO {
  input output bool A;
  input output bool B;
  output bool O1;
  output bool O2;
  region:
  
  initial state Init
  --> WaitAB immediate with / O1 = false; O2 = false;
  state WaitAB {
    region HandleA:
    initial state WaitA
    --> DoneA  immediate with A / B = true; O1 = true;
    final state DoneA;
    region HandleB:
    initial state WaitB
    --> DoneB with B / O1 = true;
    final state DoneB;
  }
  >-> GotAB with / O1 = false; O2 = true;
  state GotAB;
}

Instead of using the compiler inside the KIELER tool itself you can also use the command line version or use our new SCCharts online compiler.
