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.

Ist doch ok so, oder?

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.
