Description
Keywords: TPSYNC, TNM, ucf, constraint
Urgency: standard
General Description:
MAP may give the following for a design that has a TPSYNC orTNM attached to a loadless signal:
FATAL_ERROR:baste:bastetspec.c:908:1.64 - No pins of NC_SIGNAL $1I1/myblock/n1614 belong to NC_BEL $1I1/myblock/n1625 Process will terminate. Please call Xilinx support.
Solution
Look in the .mrp and .bld report to make sure the TPSYNC or TNM is not attached to a net that is loadless. Be careful when using wildcards (NET $1I1/mynet* TPSYNC=MYTP1); if the wildcarded constraint includes dangling nets, you may see this problem.
If this is the problem, refine your constraint so it does not include any dangling nets.
