question about IP cache versus RTL-only update

Hi All,

 

Further to the following thread: http://forums.xilinx.com/t5/Design-Entry/VIVADO-2015-2-IP-OOC-synthesis/td-p/640554, I want to better understand the meaning of the IP cache in the context of the explanation given on the bottom of the pages 25/26 of the UG896 (VIVADO 2015.2).

 

Basically, the question is, what constitutes a cache hit? If an IP has a different RTL but the same IP properties, will the cached synthesis be used for that IP or not?

 

Finally, let's say I am reloading the BD through deleting the $BD.bd file and sourcing $BD.tcl, I can see the IP OOC runs are reset. Will in this case an IP cache be used or not?

 

Thanks

Vlad
