Do we need to set uncertainty on generated clocks also ?

Are there any other mandatory constraints we need to set on generated clocks ?

Please explain.
 

yes.
As tool don't have idea that generated clk is up scaled or down scaled. So tool can not take same(master clk) uncertainty value on the generated clks.
 

Thanks Viju. Are there any other constraints required to be set on the generated clock ?

Is It like that? Are the constraints not propagated? I think we dont need to set constraints on generated clocks..Please correct me if I'm wrong
