IEEE 1076-2008 - Where do you stand Xilinx?

The IEEE 1076-2008 standard was finalised almost 3 years ago, and still there seems to be no support for most of the features in XST, why, is 3 years not long enough?

 

What I would like to see is somewhere on the Xilinx website a formal statement outlining what the stance on IEEE 1076-2008, will it be supported in upcoming versions of XST, and if so in which version?

 

Does anyone, particularly Xilinx Employees, know anything about this?

Re: IEEE 1076-2008 - Where do you stand Xilinx?

Hi,

the official release date of IEEE Std 1076™-2008 was 26 January 2009.

So, that's just about two years up to now.

 

But this is just the LRM. Good for working on the parser, but merely useless to create a synthesis tool.

The last official release of the VHDL RTL Synthesis Std. IEEE Std 1076.6 dates back to 2004, and a new revision is hopefully in work and released soon. And that's the time when conpliance tests for a tool can be done, provided that some coding has been done before.

 

And while ISIM, as a simulator,  could support VHDL-2008, it would make no real sense to diverge the supported standards between simulation and synthesis tool.

 

For Xilinx it would probably be more intersting to know which parts of the new standard you need most urgently for your synthesis. (e.g. support of numeric_std_unsigned)

 

Have a nice synthesis

Look at how long it took VHDL'93 to be widely adopted. Expect VHDL'2008 support sometime in  2014.

 

----------------------------Yes, I do this for a living.

Xilinx has a horrible track record here. SystemVerilog draft was completed 5/13/04.  Still no support

almost 7 years later.  Many missed promises on when it would be supported.
