Can I generate licensed cores in CORE Generator when using Remote Desktop?
CORE Generator, as well as the ISE implementation tools, can be run over remote desktop. However, in order for a licensed IP to be generated (or implemented in a design), the license needs to include the TS_OK tag.
Xilinx IP licenses generated after September 2008 should include this tag. Older licenses (without the TS_OK tag) need to be regenerated in order to be used from a remote desktop.
