No binary/Encrypted TCL(tcl compiler) support in all cadence tools, but Yes in Synopsys!

iceda

 Currently everybody is talking out IP protection, including all TCL commands, but it seems that Cadence didn't do good job for this kind of IP proctection unlike synopsys. Now all byte-code TCL is supported very well in all synopsys tools, but not a tiny support in all cadence tools!

    Hi iceda,

    not sure what you are talking about. All Cadence tools support the encryption outlined in IEEE1800, System Verilog LRM. In SV you can also use `pragma protect compiler directive which is supported by Cadence tools as well. Needless to say the same encryption scheme can apply to VHDL and other languages supported by Cadence tools. Not only that but tools also support partial encryption of files, different protection levels, and in many cases, encryption of TCL as well. Furthermore, in my experience, the Synopsys encryption scheme does not interoperate with any other vendors as described in IEEE1800. Maybe I missunderstood you message and can clarify.
