OCP-IP Releases Functional Coverage Guidelines; Guidelines Eliminate the Need for "Best Guess" Verification By Engineers
PORTLAND, Ore.—(BUSINESS WIRE)—June 13, 2006—
Open Core Protocol International Partnership (OCP-IP)
today announced the availability of Functional Coverage guidelines.
Functional Coverage is a technique to measure the quality of the
stimuli generated by a verification test suite. It provides an
objective view of the verification space and is used to measure the
completeness of the verification of an OCP IP block. The guidelines
eliminate the need for "best guess" verification by engineers making
certain an OCP interface complies with the current OCP 2.1
specification, assuring verification quality and IP block
compatibility at system level.
In a pseudo-random based verification environment in which the
stimuli are randomly generated within a set of constraints, a solid
Functional Coverage indicates which parts of the state space were
covered, and which parts were not. For the uncovered corners, the
generation constraints must be tightened, or specific directed tests
must be written.
Work on the Functional Coverage was completed by the OCP-IP
Functional Verification working group including representatives from:
Jeda Technologies, MIPS, Sonics Inc, Synopsys, Texas Instruments,
TransEDA, and Yogitech. This work compliments a set of formal
compliance checks already released by the FVWG in October 2005.
"The new coverage guidelines make it easier for engineers to have
even greater verification coverage as a part of the OCP socket," said
Jeroen Vliegen, System Engineer for Texas Instruments and member of
the OCP-IP Functional Verification Working Group. "It was a pleasure
leading the collaboration between such productive members of OCP-IP's
FVWG."
"The configurability of the OCP protocol fits naturally with
today's Functional Coverage driven verification methodology," said
Steve McMaster, Senior Staff Engineer for Synopsys and Chairman of the
OCP-IP FVWG. "It was a pleasure to participate in this important work
with such a dynamic group."
"Presenting defined functional coverage guidelines to the industry
further strengthens the value and utility of the OCP standard," said
Silvano Motto, CEO of Yogitech. "This significant accomplishment was
made possible by the expert contributions of the OCP-IP FVWG team, in
which I am very proud Yogitech participated as a verification IP
provider."
"The guidelines produced by our Functional Verification Working
Group are yet another extremely valuable addition to OCP-IP's robust,
thriving infrastructure," said Ian Mackintosh, president OCP-IP. "We
are proud of the leading-edge work completed by our Functional
Verification Working Group."
