RE: [sv-bc] Query related protect dirctive which is present in VHDL-2008 but not in verilog/System verilog.

It is organized a little differently in System/Verilog. The protect directive exists as "`pragma protect".

The description is the BNF from the `pragma compiler directive in 22.11, and examples and textual descriptions and tables in Clause 34.

Hi Shalom,
Nope, I did not see that type of rule in either Verilog 2005 LRM or System Verilog LRM. Can you please specify any particular sub-section mentioning that similar rule as I mentioned in my last mail.

Regards
Surya

I was referring to the SV-2009 LRM.

The corresponding sections in the Verilog-2005 LRM are 19.10, 28.3 and 28.4.

Hi Shalom,
To be specific, in VHDL 2008 LRM, there is a BNF for encryption_envelope as:
encryption_envelope::=
    { encrypt_specification }
    protect_begin_directive
       source_text
    protect_end_directive

This type of rule is missing in any version of Verilog/System Verilog LRM. Also I could not match this with the section number you mentioned. Please let us know your comments on that.

Regards
Surya

See section 22.11 for pragma directives in general and sections 34.4 and 34.5 for protect pragmas in particular.

Hi Shalom,

Might my query was not clear. What I want to know is this that in VHDL-2008, protect directive
has encryption envelope and decryption envelop and those envelope has BNF mention there. i.e what
are the different thing that an encryption or decryption envelope can have but SV-2009 don't have
that kind of BNF.

So my query is this that was it overlooked??.

Hi,

I have a query related protect directive.

In VHDL-2008,there is a directive named "protect directive" which is
used for
encryption/decryption of the source text.

In SV-2009,there is nothing like protect directive of VHDL-2008.

So my query is this that whether it is not necessary in
Verilog/System
verilog or it was overlooked??.

Regards,
dhiRAj
