115 -Now generate the Sequentially Constructive Graph (SCG) from the normalized form. You do this also in the context menu of the Project Explorer by selecting the *.normalized.sct and choosing Generate SCG:

119 -When selecting the abo.normalized.scg file the SCG diagram will be automatically synthesized (you may also want to re-arrange the KLigD view by dragging in to the right side again):

123 -You can now populate the SCG automatically with dependency data. Choose Transform SCG -> SCG with Dependency Data from the context menu:

127 -This will result in the following SCG:

131 -Now populate the SCG with basic block information:

135 -The SCG with calculated basic blocks will look like this:

147 -The SCG is now ready to be sequentialized. A primitive scheduler currently is included in KIELER but more elaborate ones are already in the pipe line:
