Archived ISE issues

[arsierra]

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.

If I understand correctly this line indicates only information.
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)
