Einige Erfahrungen mit Embedded Coder

- Sehr gute Erfahrungen mit Modellcode => Keine Fehler bei Unit Tests

- Gut: Typen können mit Slopes versehen werden => automatische

Umrechnung in und von SI-Einheiten

- Wichtig: S-Functions und Legacy CodeTool ermöglicht Einbringung

handgeschriebenen Codes

- Schnittstellendefinition (Inputs/Outputs) ok, aber noch oftmals zu steif

(get/set-Funktionen)
