WARNING:basts:158 - PERIOD TIMESPEC 'TS_gclk1' has TIMEGRP 'gc1_grp' which contains only PAD elements. This capability will soon be obsoleted as it has been replaced by the TNM_NET constraint.
WARNING:basts:157 - PERIOD TIMESPEC 'TS_gclk' has
TIMEGRP 'gc1_gr[' which contains a mixture of PADs and
synchronous elements. The PADs in this group will be exempt from
analysis by the trce application. The ability to mix PADs and
synchronous elements in a PERIOD group will soon be obsoleted.
This warning was intended to be a feature, and is not a bug. The
warnings are generated because the user is using a TNM on the
net before the BUFG, rather than the new TNM_NET constraint.
If you use TNM_NET, the warnings will go away. The PERIOD
constraint is changing in 2.1i, to not include the PAD elements
in the period constraint. The period constraint will only cover
from synchronous elements to other synchronous elements.
For information on TNM_NET and PERIOD see the Developmental
Reference Guide in the On-line Docs.
