Hallo alle zusammen,
ich probiere den USB2.0 Core zu sybthetisieren, aber es klappt
irgendwie nicht. Der Xilinx ISE 7.1 zeigt mir andauernd irgendwelche
warnings:

Den Synopsys Script habe ich auch schon ausprobiert, doch da sind auch
warnings.
Hat jemand Erfahrung mit diesem USB-Core???????

Freue mich auf alle Antworten !!!!

Hallo Raymen

"is never used" :-?  :-?

Was hast du den überhaupt mit der externen Logik verbunden?
Hier mal die Liste, was noch nicht angeklemmt ist.

Input <int_to_set>   Input <clk>          Input <uc_bsel_set>
Input <din>          Input <buf0_rl>      Input <buf0_set>
Input <rst>          Input <int_buf0_set> Input <idin>
Input <wclk>         Input <buf1_set>     Input <int_buf1_set>
Input <re>           Input <out_to_small> Input <dma_ack>
Input <adr>          Input <we>           Input <uc_dpd_set>

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????
