[TimeQuest] false paths to/from/inside an hierarchy -> how to?

[Altera_Forum]

Hi All, 

 As for the TimeQuest, how can I put a false path for all the signals coming to/from a specific hierarchy and also for the signals inside of the hierarchy?   Thank you

set_false_path -to {*entity:inst|*} 

set_false_path -from {*entity:inst|*} Change the wildcarding as appropriate.

Thanks! Thanks! Thanks!

Would these commands also apply false paths between flops inside of the hierarchy?

[Altera_Forum]

This would ONLY apply between flops, as that is all that is timed (except IO pins).  

What are you trying to cut? you realise that false paths basically just set an ignore list for timequest. You should be careful with false paths and ensure there really is no timing relationship between the two flops.
