+Current version of this version Reg is `1`. Use this tcl script for Vivado synth-pre-tcl: [set_BuildVersion.tcl](/uploads/9fdf1898a1797857e11889134c5179d0/set_BuildVersion.tcl)
+
+Generics
+********
+
+| Name | Description |
+|-------|----------|
+| VERSION_FILE_NAME | Path to the Version-mem-file created by `set_BuildVersion.tcl`. Relative to `constant MY_PROJECT_DIR` in `src/PoC/my_project.vhdl` |
+| HEADER_FILE_NAME  | If csv-file with all register spaces is needed, put here the name/path of csv-file. Relative to `constant MY_PROJECT_DIR` in `src/PoC/my_project.vhdl` |
+| INCLUDE_XIL_DNA | Includes Xilinx-DNA-Port. Working for 7-Series and US/US+ Devices. Note: 7-Series has 32 times this "unique" ID. |
+| INCLUDE_XIL_USR_EFUSE | Includes Usr-EFuse. {-Currently not Implemented-} |
+| USER_ID               | 96bit ID, which can be set through PL in synthesis. |
+
+Register Map
+************
+
+All Registers are Read-only. Version Register should always start with offset `0x80000000` (First PL Address).
