Standard implementation of constant, copyright or not ?

[Bastien ROUCARIES <roucaries.bastien@gmail.com>]

Hi,

I plan to package adms on the behalf of debian science in order to package qucs.

I have a legal problem:

Some file are :
  Copyright <A9> 2007Accellera Organization, Inc.
  Standard definitions
  This file contains the standard definition package constants.vams
for Verilog-AMS HDL.

Extracted from standard book
http://www.eda.org/verilog-ams/htmlpages/tc-docs/lrm/2.0/stddef.html

The file is here:
https://github.com/upverter/ADMS/blob/master/admsXml/constants.vams

I do not believe it is copyrightable.

What is the legal status? How can I document on debian/copyright ? Do
I need to do a clean room implementation ?
