Dear members of CC,
I thank Michael McNamara for disclosing the patent on this topic.
This patent disclosure is now an Accellera board business and it should not
affect the process that we have started in this committee.
The committee should continue the discussion and also the voting
that has started by the chair. On a technical basis, we will examine the
patent(s) that Verisity has disclosed and see if (it) they pertain to the
syntax or semantic of the API. If it pertains to implementation of an
algorithm, then it is does not pertain to the topic at hand. If it pertains
to Syntax or Semantics we can change what we have so that we do not conflict
with the patents.
We had a similar situation on Verilog-A where Cadence failed to
disclose a patent on the syntax at the beginning of standard development.
They disclosed the matter near the end of the standardization process. At
that time we had the option to develop new syntax and/or negotiate a free
license on the patent. The board decided to work with a free license on
Verilog-A.
In summary, please do not let such an email affect your voting
confidence. The voting process will continue. We will also continue our
technical discussions on the donations. We will report more on this topic,
as more materials is made accessible to us by Verisity.
Best Regards
Vassilios Gerousis
