Problem Title: INTERNAL_ERROR:baste:bastetspec.c:2325:1.69.14.3 - TE_TS_SIG object associated with NET EVNT_EVEN1 has no associated NC_SIGNAL. Problem Description: Urgency : HOT General Description: Map error out with the following error if maxdelay or maxskew is attached on a net: INTERNAL_ERROR:baste:bastetspec.c:2325:1.69.14.3 - TE_TS_SIG object associated with NET EVNT_EVEN1 has no associated NC_SIGNAL. or INTERNAL_ERROR:baste:bastetspec.c:2307:1.69.14.3 - TS_NET_TIMING object associated with NET EVNT_EVEN has no TE_TS_SIG. Solution 1: The internal errors can be safely ignored. M1.5 still generates a good .ncd file despite this error. The error was caused by optimization. OPTX has been run, and has found some pairs of nets that have identical function. It only preserves   one net in each pair in the NCD. However, both nets have identical MAXSKEW constraints and the co nstraint on the net that was dropped has not been moved to the net that was preserved. This is caus ing the internal error. Since the net constraints are identical in each net-pair, and the constraint on the net being retained is properly processed, there is no loss of function. Turning off optimization (-oe and -os) causes the internal errors to disappear. This error has been scheduled to be fixed for the A2.1 release. End of Record #4301 - Last Modified: 09/26/98 16:15
