Quartus II 9.1 SignalProbe Compilation

Hi,

I am working on a script file to support SignalProbe compilation.

The operation sequence is:

check_time

echo -e "$CUR_TIME: Compilation flow starts..."

quartus_sh --flow compile $PROJ_NAME > $LOG_FILE_NAME

echo -e "$CUR_TIME: Restore SignalProbe Setting!"

quartus_cdb -t signalprobe_qsf.tcl

echo -e "$CUR_TIME: Running SignalProbe Compilation!"

quartus_sh --flow signalprobe $PROJ_NAME > $SP_LOG_FILE_NAME

But Quartus gave me this error message:

Can't perform SignalProbe compilation because design requires a full compilation. To perform a SignalProbe compilation, recompile the design.

I thought i just finished the full compilation.

Does anybody know what i did wrong here?

thanks.
