The Vivado synthesis tool provides a cache
that preserves synthesis results for reuse in other designs that use the same IP
customization. In Project Mode, this caching applies to the OOC synthesis flow. In
Non-Project Mode, the synth_ip command provides
equivalent caching. This cache can significantly speed up synthesis of large, complex
designs. For more information, refer to Setting the IP Cache in
Vivado Design Suite User Guide: Designing
with IP (UG896).
