Hallo, ich hab alle eingänge von mein FPGA benutzt und nun kommt diese Fehlermeldung. Komme einfach nicht mehr weiter. Kann mir da jemand sagen, was ich tun muss? ERROR:Place:866 - Not enough valid sites to place the following IOBs: IO Standard: Name = LVCMOS25, VREF = NR, VCCO = 2.50, TERM = NONE Module_CLK This may be due to either an insufficient number of sites available on the device, too many prohibited sites, or incompatible I/O Standards locked or range constrained to I/O Banks with valid sites. This situation could possibly be resolved by one (or all) of the following actions: a) Grouping IOBs of similar standards into a minimum amount of I/O Banks by using LOC or range constraints. b) Maximizing available I/O Banks resources for special IOBs by choosing lower capacity I/O Banks if possible. c) If applicable, decreasing the number of user prohibited sites or using a larger device.
Jede Bank von Ausgaengen des FPGA kann nur einen IO Standard, z.B. LVTTL oder LVCMOS, erzeugen. Du benutzt an einer Bank unterschiedliche Standards - in den meisten Faellen ist das gar nicht noetig, oder warum hast du unterschiedliche Standards ausgewaehlt? Loesung ist also, in den Contraints mehr Ports den gleichen Standard zuweisen.
ich hab eigentlich nur gleiche Standards benutzt. __ # Constraints for reference design 'PCI Bridge' # # Ena Echlas - June 2008 # # # Period constraint for 66MHz to 33MHz operation # # # MPC5200 66MHz Clock for PCI NET "MPC5200_CLOCK" PERIOD = 15.15ns HIGH 50%;

Vielleicht fehlt ein Port und wird standardmäßig auf LVCMOS25 gesetzt?
Kannst auch einfach das hier schreiben: NET "*" IOSTANDARD=LVTTL; Das gibt zwar ein paar Warnings, weil die ISE dann versucht, auch die Stromleitungen auf LVTTL zu legen, was natürlich nicht geht, aber diese Warnungen kannst du getrost ignorieren und bist sicher, dass überall LVTTL anliegt, ohne das mühsam für jeden Pin zu schreiben.
@Anfänger: Hast Du alle Ports Deiner entity auch im .ucf? Wenn da mehr drin stehen sucht ISE automatisch einen freien Pin (eh keine gute Idee) und nutzt dort den default IO-Standard. Rick
Nein, ich hab nicht alles Pins. Aber trotzdem bekomme ich diese Error. Mist, das bedeutet doch das er die LVCMOS25 nicht routen kann. Kann mir jemand sagen was ich noch tun kann?
