#187962 - this warning...
Responding to: Mahmood Elnasser's previous message
WARNING:Xst:753 - "C:/Projects2012/spartan3e brd/DCM/DCMtry1/try1/try1/pulsegen.vhd" line 25: Unconnected output port 'CLKIN_IBUFG_OUT' of component 'myDCM'.

WARNING:Xst:1780 - Signal <cigo> is never used or assigned. This unconnected signal will be trimmed during the optimization process.
However when I implement the design I get this error message:
ERROR:NgdBuild:604 - logical block 'Inst_myDCM' with type 'myDCM' could not be
resolved. A pin name misspelling can cause this, a missing edif or ngc file,
case mismatch between the block name and the edif or ngc file name, or the
misspelling of a type name. Symbol 'myDCM' is not supported in target
'spartan3e'.

is down to coregen loosing or corrupting it project file, it happens all the time which is another reason i don't use coregen.
