Hallo, Kann man Tristate Ausgänge schon im CPLD verbinden? Konkret geht es um diesen Fall: Die Datei "real" zeigt die funkt. Schaltung mit den rot umkreisten 74HC4094. Diese möchte ich in ein CPLD schieben, siehe Datei "cpld". Wobei ich auch gleich die Ausgänge der beiden 74HC4094 im CPLD so verdrahten will wie in der "realen" Schaltung. Die Syntese und das Fitting läuft durch, nur bringt er eine Warnung,siehe unten. Kann man das ignorieren? Würde das trotzdem funktionieren? Oder wie müsste ich die Schaltung im CPLD umändern?
