OCI Approved by Accellera
Today, Accellera has approved the Open Compression Interface standard (OCI version 1.0). See the EE Times article by Richard Goering here.
Back in Test Compression Series - Installment #2, I made brief mention of OCI, which is an effort that was undertaken by Accellera due to a need in the industry for flexibilty in test compression solutions. At this time, test compression implementations come in tightly bound pairs consisting of compression IP and ATPG software; both must come from the same company. This poses problems especially for silicon targeted for more than one foundry, where the different foundries support different yield diagnostics software.
The OCI breaks the need for pairing the IP and software by defining a common interface, which provides just enough information about the compression IP so that any ATPG tool can understand how to generate vectors, but not so much as to give away the secrets of the IP’s implementation.
Next stop, IEEE standards process. Who’s on board?
