Please call Xilinx support. Solution 1: Current workaround: Try increasing the Collapsing Input Limit, this switch is in DM/FlowEngine -> Options -> Edit Templ ate -> Advanced Optimization. Default setting for this in M1.4 is 36 and specifying lower input limit may cause the optimizer impo ssible to fit the design and can result in fatal error. This issue has been resolved in M1.5 End of Record #3686 - Last Modified: 04/08/98 17:22
