159 In the following, you find some examples used for evaluation. Be advised that there currently is no tool integrated evaluation possible. Please refer to the SCCharts superpage for the [[project status>>doc:KIELER.SCCharts.SCCharts (DeprecatedHistorical Documentation).SCCharts (pre 1\.0).WebHome]] and [[known limitations>>doc:KIELER.SCCharts.SCCharts (DeprecatedHistorical Documentation).SCCharts (pre 1\.0).WebHome]]. You may use our [[online compiler>>doc:KIELER.SCCharts (DeprecatedHistorical Documentation & Features).SCCharts (pre 1\.0).Online Compiler.WebHome]] or the [[command line compiler >>doc:KIELER.SCCharts (DeprecatedHistorical Documentation & Features).SCCharts (pre 1\.0).Command Line Compiler.WebHome]]to play around with the following SCCharts. On the right side you'll find the textual SCChart (SCT) description, on the left side you see the equivalent synthesized SCChart diagram for it. You can use our [[online SCChart synthesis>>doc:KIELER.SCCharts (DeprecatedHistorical Documentation & Features).SCCharts (pre 1\.0).Command Line Rendering.WebHome]] for rendering SCCharts diagrams from textual SCCharts descriptions.
