Description

Keywords: VHDL, package, endfile, read, readline, 8.1i

XST exits when the last line of the following code for reading from a file is passed:

while (not endfile (MY_FILE)) loop
readline (MY_FILE, MY_LINE);
read (MY_LINE, MY_DATA);
end loop;

The following error occurs:
"ERROR:Xst:1923 - Line <MY_LINE> has not enough elements for target <MY_DATA>".

Solution

To resolve this issue, recode with the following:

while (not endfile (MY_FILE)) loop
readline (MY_FILE, MY_LINE);
exit when endfile (MY_FILE);
read (MY_LINE, MY_DATA);
end loop;

This issue will be fixed in the future releases of ISE.
