Solution
This may be the result of a carrychain loop. For example: the Cout of a counter feeding the Cin of the same counter.
For now, the user must manually break the carrychain loop. put a BUF between the final Cout and the first Cin. Then put keep attributes on the nets connected to the the BUF.
This problem is fixed in version 2.1 due out in June, 1999.
