Expert VHDL Expert VHDL ist ein intensives 5-tägiges Fortgeschrittenentraining. Entwickler steigern mit diesem Training die Produktivität durch Ausbau von VHDL-Codierungs- und -anwendungsfähigkeiten. Der Fokus in den zwei unabhängigen Modulen liegt auf Sprache und Synthese, Wartbarkeit und Wiederverwendbarkeit des Designcodes, Testbenches und den neuesten Verifikationstechniken - incl. einer Einführung in OVL/PSL und OSVMM und UVVM.
Die Module können als Komplettkurs oder einzeln besucht werden. Sie bauen auf dem Doulos Industriestandard-Kurs "Comprehensive VHDL" auf. Sorgfältig entwickelte praktische Übungen machen ca. 50 % des Trainings aus und verfestigen das Erlernte im Kontext der aktuellsten Tools, Verfahren und Methoden.

Die verfügbaren Tools für einen geplanten Kurs können variieren. Präferenzen können im Buchungsprozess ausgewählt werden. Oder wenden Sie sich bitte an Doulos, um spezifische Anforderungen zu besprechen.
Um den größten Nutzen aus diesem Fortgeschrittenentraining ziehen zu können, ist die Teilnahme an Doulos Comprehensive VHDL oder vergleichbarem Training sowie mindestens 6-monatige Erfahrung mit VHDL erforderlich. Teilnehmer am Expert Design-Modul benötigen Vorkenntnisse in RTL-Codierung und Synthese mit VHDL.
Die Doulos-Kursunterlagen sind für ihren umfassenden Informationsgehalt und die benutzerfreundliche Präsentation allgemein bekannt.
