CORE Generator - Generation time increases when VPN adapter is used for licensing


Decreasedperformance is observed when I open the CORE Generatorsoftware and generatelicensed coresif there is an ISE Design Suitesoftware licensenode locked to a VPN adapter. It does not matter if the ISE Design Suiteinstall is local or remote. The order of license checking also does not seem to matter.
Oncethe VPN adapter is shut down,standard performance is observed.


Node lockinga license to a VPN adapter provides some flexibility (similar to a license dongle). However, it is not arecommended use model for Xilinx licensing.
CORE Generator performance can be maintained by using anon-VPN address or disc serial number for the ISE Design Suitesoftware license.Having other licenses, including that of the IP being generated, locked to the VPN adapter does not seem to cause an issue.
