The USERCODE JTAG instruction allows you to set a 32-bit design-specific identification code that can be accessed over JTAG. The USERCODE can be programmed into the device and can be read back for verification later as part of the device registers in the Vivado Hardware Manager or by reading the JTAG instruction register.
The USERCODE value can be set at the Tcl console with the following CIPS IP
Property:
