Hallo alle zusammen, ich probiere den USB2.0 Core zu sybthetisieren, aber es klappt irgendwie nicht.

Hallo Raymen "is never used" :-? :-? Was hast du den überhaupt mit der externen Logik verbunden? Hier mal die Liste, was noch nicht angeklemmt ist.

Hallo an alle! Danke erstmal für eure antworten!! Die Seite von der ich dieses Core habe ist: www.opencores.org/projects.cgi/web/usb/overview Die Signale die da gezeigt werden mit "is never used" sind eigentlich die Internen Signale. Würde mich für weitere Antworten sehr freuen!!!! MfG Raymen
Du hast aber alle Einträge der Entity des Toplevels miteinem Ausgang "verbunden"? Sonst versucht er nämlich die nichtverwendeten wegzukürzen. Aber ich schau mir das die Tage noch mal in ruhe an. ich habe ihn aber bis jetzt noch nicht benötigt. Cores von Opencores.org sind aber eigendlich sehr gut geprüft. Wenn fehler entdeckt werden, wird nen Käfer eingeblendet.
Wie meinst du es mit einem Ausgang????
