Also, ich sitze jetzt auf dem Holzmarkt und jetzt mache ich den Registersatz fertig.
Ah, es sieht so aus, als hätte ich den Fehler gefunden, er liegt in der Testbench. CLK ist postivie Taktflanke. Die Testbench ging nicht weit genug.
Nein, es scheint zu tun, die Testbench war falsch.
Also, es tut doch, sorry, ich war draussen, das Smartphone hatte Akku leer und ich keine Internetverbindung
Es tut, die Testbench war falsch.
