FILE usage in xilinx ISE Software giving errors

[drba]

i am using ise 9.1 .
i tried a vhdl program to read the data from one file and write manipulated data to another file.
i am getting xst:1914 error.FILE<FILENAME> doesn't exist.
However, the mentioned file exists in the corresponding location.

are you just simulating or trying to synthesise?
If ISE cant find the file, you got the path wrong.

hi,

i am trying to synthesize it.
destination path is also correct.
i tried by placing the file in the other drive
location as well as with in the project file location .
But the result is same.

Just as a note - if you're using fileIO in VHDL - be aware it is not appropriate for synthesis, other than for seting up ROMs and RAMs.
