1.12.2.2. Using Supported Simulator Mode for IEEE1735 Encryption

The IEEE1735 Standalone Encryptor can also encrypt a file to be read into simulators that the Quartus® Prime supports.
Refer to Supported Simulators for the current supported list.

In Supported Simulator Mode takes the Encryptor takes in one source file, and then generates one encrypted file. The --simulation option encrypts the files for all four supported simulators simultaneously. To encrypt for only one or more specific simulators, specify the simulator by specifying a value for the --simulation option. The valid options are aldec, cadence, mentor, synopsys.

  1. Use one of the following commands to use Supported Simulator Mode for encryption. Use a comma delimiter to specify multiple simulators. Do not enter spaces between the options. For example, --simulation=aldec,cadence.
    • Verilog HDL:
      encrypt_1735 --simulation --language=verilog <file_name>.v
    • VHDL:
      encrypt_1735 --simulation --language=vhdl <file_name>.vhd

    The Encryptor creates an encrypted file with the same file name, but with a new extension, such as some_file.vp and some_file.vhdp.

  2. To optionally change the name of the output file name, specify the -o option. For example:
    • Verilog:
      encrypt_1735 --simulation --language=verilog -o=<new_file_name>.v \
         <file_name>.v
    • VHDL:
      encrypt_1735 --simulation --language=vhdl -o=<new_file_name>.vhd \
         <file_name>.vhd
    The Encryptor generates an encrypted <new_file_name>.v file or <new_file_name>.vhd.
    Note: If you are encrypting files that are called by name in other parts of the source code, such as Verilog `include files, you must use the correct encrypted filename when you reference the files. Use the -o option to create the encrypted file with the original filename, so that the name does not include the default “p” in the extension (for example, <included_file_name>.v instead of <included_file_name>.vp).
