Re: [1076.1] Information on proposed IP support in VHDL-200X

Hi,

I have a little additional information. What Lance(in prior email) and 
Victor suggest appears to be true.  Synplicity took a draft from 1364 
and modified the pragma prefix to be "%%%" and used that unchanged in 
each of Verilog, VHDL, and EDIF.  They describe a subset of the 
mechanism, the digital envelope with a straightforward model for 
managing keys.  It is unclear but probable that they only have a subset 
of the mechanism implemented.  It seems right to me to begin promoting 
adoption of this approach as development continues.
I believe they also added some pragma's to direct tool output (e.g., 
synthesized or derived netlist ) to be reencrypted. 

Let's see what results from Victor's discussion, but it should be 
straightforward for them to align themselves to the standard. It would 
be useful  to encourage them to review and give feedback on the VHDL LRM 
in this area, Lance.

Regards, John Shields
