Unencrypted:

Just directly run write_bitstream based on the opended implementation result:

write_bitstream xxx.bit.

 

Encrypted:

Refer to Xapp1239 or Xapp1267:

https://www.xilinx.com/support/documentation/application_notes/xapp1267-encryp-efuse-program.pdf

Briefly, set a bunch of properties before you run the write_bitstream command in the Tcl console. Don't save these to the design, and you will always get a 'clean' dcp file.

Thank you for your reply.   It is solved.

After changing the setting in "Edit Device Properties", "Generate Bitstream" was executed from "Flow Navigator".

The modified bitstream was created by running from "Tcl Console".
