4.1i Virtex-II MAP - Use of the "-timing" option is corrupting the timing constraint unit


Keywords: timespec, units, -timing, corrupt

Urgency: Standard

General Description:
It has been found that MAP will corrupt the value of any frequency-based timespec if it is defined in a unit other than picoseconds and the timing-driven map feature is being used.



This problem is fixed in the latest 4.1i Service Pack, available at:
The first service pack containing the fix is 4.1i Service Pack 3.


The work arounds are to either not use the timing driven map feature or to specify all frequency based timspecs in pico seconds.
