Mentor welcomes interactions between Calibre and third party tools, which is why we have the Mentor OpenDoor partner program to ensure access for other EDA vendors, and quality interfaces for our mutual customers. Quality assurance testing and certification is a big part of that program. Consequently, we feel obliged to inform readers when those expectations are not met.
Tanner EDA is currently not a participant in Mentorís OpenDoor program, and the External Verification Interface described in this article is not validated or supported by Mentor Graphics. With the growing complexity of advanced verification flows, users should be concerned about errors in the transfer of data between tools, and they should expect that interoperability interfaces are thoroughly tested by all the vendors whose tools are party to the exchange.
One of the most pernicious problems with tool interoperability is file skew--a prerequisite file, like a library or a verification result that is out of date. Once it gets into your data, file skew causes subtle errors that necessitate a tremendous amount of rework.
How does your Tanner-Calibre interface address file skew?
