Timsim8 may issue the following warnings while running PLD_DVE_BA:
pld_dve_ba ack ack.mba Delete operation on object /home/tony/ack/default (Eddm_ba_mgr) failed Object /home/tony/ack/default (Eddm_ba_mgr) not accessible
These messages do not appear in the timsim8.log file.
To annotate timing information back to the original schematic, Mentor creates a "back-annotation object" based on information returned from XNFBA. To do this, PLD_DVE_BA (PLD Design Viewpoint Editor Back Annotate) first tries to delete any existing back-annotation object, then generates a new object from the XNFBA-generated .mba file and links it to the default simulation viewpoint. The problem is that PLD_DVE_BA does not check to see if a previous back-annotation object exists before going ahead with the delete operation. Therefore, the delete operation will "fail" if nothing is available to delete.
On subsequent Timsim8 runs, the messages disappear, since back-annotation objects do exist from previous runs. These warnings do not affect timing simulation, so you should be able to run Quicksim without any problems.
