BEAVERTON, Ore. — (BUSINESS WIRE) — May 23, 2012 — Open Core Protocol International Partnership (OCP-IP) announces the release of their newly updated Compliance Document, including the latest comprehensive set of Functional Checks and Assertions for member review. The latest version of the Compliance Document includes support for OCP’s existing cache coherence extensions, as well as the new memory barrier and transaction counting extensions introduced in the OCP 3.1 Specification.
Protocol compliance checks ensure that interface behaviors are consistent with OCP, and can be as simple as "check that a signal is never X" or may be complex temporal expressions. Configuration compliance checks ensure that the OCP interface is legally configured. Functional coverage points provide categorization of the types of signal and transaction combinations that need to be covered for complete verification. An OCP-based IP block that passes the configuration checks and is verified to cover all of the functional coverage points without violating any protocol checks is proven compliant with the protocol.
The compliance checks can be used in several different ways. Formal tools can use checks to be sure a design never violates them, proving OCP compliance. They can also use the same checks to cover the number of times a given constraint was hit. Functional verification tools can use the properties to build protocol checkers (in System Verilog/VHDL/e/SystemC, etc.). By applying stimuli to the design under test (DUT) and verifying that protocol checkers are not reporting violations, OCP compliance is verified.
“OCP-IP is committed to providing a complete infrastructure surrounding the OCP Specification, which allows users to readily deploy OCP,” said Ian Mackintosh, president and chairman, OCP-IP. “In addition to our own CoreCreator®, OCP Tracker®, and OCP Conductor® verification tools, and documented checks, there is a large range of proven products available from commercial providers. These tools eliminate the need for ‘best-guess’ verification by engineers.”
The Compliance document is available free to paying OCP-IP members. Non-members may purchase the document to assist them in verifying their OCP designs by completing the Compliance Document RLA ( http://www.ocpip.org/compliance_rla.php).
