Seperate flow for Synthesis+P&R for a ceratain hierarchy in design -> is this possible?

Hi All,

I have some hierarchy in my design with timing violations.

How could I make this hierarchy as a Black Box, so it would be still an inherent part of the physical flow (P&R), yet be synthesized separately?

Thank you!

Hi @ldm.eth ,

Are you looking for incremental compile flow?

Please check this AR#:

You can select this piece of hierarchy in Sources window and select "Set As Out-Of-Context for Synthesis" option in the right-click menu. 

For more description, please have a look at UG901, pg23, section "Setting a Bottom-Up Out-of-Context Flow".

Hi, @ldm.eth ,

You can also consider the PR flow described in UG909.
