The Vivado connection to an XVC-Server Application should not be running when a device is programmed. The XVC-Server Application along with the associated connection to Vivado should only be initiated after the device has been programmed and the hardware PCIe interface is active.

For DFX designs, it is important to terminate the connection during DFX operations. During a DFX operation where debug cores are present inside the dynamic region, a portion of the debug tree is expected to be reprogrammed. Vivado debug tools should not be actively communicating with the FPGA through XVC during a DFX operation.
