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)
