finally I learned how to simulate the core...i added all file in the

If you don't even know how to simulate cores I wouldn't recommend 
starting with a complex one like the jpeg is...
Anyways if you are really interested and knowing that the error is: 
"ERROR:Simulator:170 - work/compressor/jpg is not compiled properly. 
Please recompile work/compressor/jpg in file "C:/Documents and 
Settings/yazdanbakhsh/Desktop/JPEG/compressor.vhd" without -incremental 
option."

I would suggest:
1) READ THE INSTRUCTIONS ON SIMULATION THAT ARE INCLUDED WITH THE SOURCE 
FILES!! (have you generated the DCT and memory cores with XilinxCoreLib? 
that's #1 mistake, sadly)
2) recompile compressor.vhd without the -incremental option :-P

Everybody who has followed the directions given in the instructions 
contained in the source have been able to succesfully use the code, they 
are not that difficult...

Regards,

Victor
