The picture shows the ABO SCChart and two possible execution traces. The signal graphs are showing the simulated ABO-hardware circuit. As you can see, it does the same .
Here clk is tick_in.
A tick starts which every rising edge from clk.
Do not note tick_in.
After the execution from ABO the hardware signals still remain.
From this we can see that it is possible to synthesize hardware from SCCharts (Synchronous C).
