Thanks,

Best regards,

Sheng

    I encrypted the hdl file with encrypt_1735(Quartus encrypt tool). So I think it is not unknown encrypted files

      @haianhle Based on internal feedback, unknown encrypted files also include Quartus encrypt tool (encrypt_1735). Feedback as below:

      Is the file encrypted with the altera key?

      If it is quartus synthesis can analyze it. Otherwise it can't.
