Since I use ISE 10.1.3 some projects have this string inside the BIT files, and I wonder where in the ISE environment it is set and what is it for.

There is now a flag is added by bitgen to the programming file so iMPACT can tell if there are any HW eval cores (that would time-out after a certain period) so the user can be warned.
Maybe you generated the bitstream on a new computer without a valid license and didn't see the warnings.
Maybe you forgot to tell your coworker it was an eval bitstream - she/he likely want to know before trying to debug why the design quit working later.

Thank you Timpe.
But I don't understand this:
- If I had HW cores in my design which require a license, bitgen should put the string HW_TIMEOUT=TRUE, isn't it?
I only use simple cores, like DPM's, comparators, FIFO's or Shift Registers.
Anyway, thanks for your answer.

I would expect the parameter to be TRUE only if you used any licensed cores that were in HW Eval mode.
Otherwise (no licensed cores or licensed cores with a full hardware license), I would expect it to be FALSE.

so... I want to ask how i can remove it (I need it because I have a script that passes the file and reads out all kinds of data and i do not that this information will be there)
