Solution 1:

Current workaround:

Try increasing the Collapsing Input Limit, this switch is in  DM/FlowEngine -> O
ptions -> Edit Template -> Advanced Optimization.

Default setting for this in M1.4 is 36 and specifying lower input limit may caus
e the optimizer impossible to fit the design and can result in fatal error.

This issue has been resolved in M1.5
