ModelSim 6.4b crashes after SDF annotation


When I run a timing simulation with an SDF file, ModelSim 6.4b crashes after SDF annotation.


If you runtiming simulation with the SDF file ModelSim sometimes issues the following warning and then crashes:

# ** Warning: (vsim-3316) No solution possible for some delayed timing check nets. 7 negative limits were zeroed. Use +ntc_warn for more info.
# Region: /test

This issueoccurs with ModelSim versions: 6.4b, 6.5c, and6.4d, and is scheduled to be fixed in ModelSim 6.5e, 6.6a.
