Tip: In Verilog and SystemVerilog, the
`pragma
protect keyword replaces the `protect keyword in
VHDL.The following example is a Verilog version of the preceding VHDL example:
`pragma protect version = 2
`pragma protect begin_commonblock
`pragma protect control error_handling = "delegated"
`pragma protect control decryption = (activity==simulation)? "false" : "true"
`pragma protect end_commonblock
`pragma protect begin_toolblock
`pragma protect rights_digest_method="sha256"
`pragma protect key_keyowner = "Xilinx", key_method = "rsa", key_keyname = "xilinxt_2019_11", key_public_key
...
`pragma protect control xilinx_configuration_visible = "false"
`pragma protect control xilinx_enable_modification = "false"
`pragma protect control xilinx_enable_probing = "false"
`pragma protect control decryption = (xilinx_activity==simulation)? "false" : "true"
`pragma protect end_toolblock = ""
`pragma protect begin
// Secure Data Block
// Protected IP source code is inserted here.
...
...
...
`pragma protect end
