wierd problem

This is what I got when I do the behavioral simulation:

 


WARNING:HDLCompiler:746 - "N:/K.31/rtf/vhdl/src/ieee/numeric_std.vhd" Line 867. Range is empty (null range)
WARNING:HDLCompiler:746 - "N:/K.31/rtf/vhdl/src/ieee/numeric_std.vhd" Line 868. Range is empty (null range)
ERROR:HDLCompiler:102 - d:/ise/learning/project/dpram/dpram/isim/work/dpram_16.vdb does not contain a known VHDL parse-tree format
WARNING:HDLCompiler:89 - "mother_board.vhd" Line 86. dpram_16 remains a black-box since it has no binding entity
ERROR:Simulator:777 - Static elaboration of top level VHDL design unit tb_mother_board in library work failed

if the problem was so simple then why did you have to post it in the forum?

once you found the solution, the problem appeared simple. May be if you could post it, somebody else would have found it useful
