The '''Open Verification Methodology''' (OVM) is a documented [[methodology]] with a supporting building-block library for the verification of semiconductor chip designs. The initial version, OVM 1.0, was released in January, 2008,<ref>[http://www.ovmworld.org/press_release_010908.php OVM 1.0 Announcement]</ref> and regular updates have expanded its functionality. The latest version is OVM 2.1.2, released in January, 2011. The current release and all previous releases are available, under the [[Apache License]], on the OVM World<ref>[http://www.ovmworld.org OVM World]</ref> site.

The reuse concepts within the OVM were derived mainly from the URM (Universal Reuse Methodology (URM) which was, to a large part, based on the [[ERM (e Reuse Methodology)|eRM]] (e Reuse MethodologyERM) for the [[e (verification language)|e Verification Language]] developed by Verisity Design in 2001. The OVM also brings in concepts from the AVM (Advanced Verification Methodology (AVM). The [[Universal Verification Methodology|UVM]] class library brings much automation to the [[SystemVerilog]] language such as sequences and data automation features (packing, copy, compare), etc.). The UVM also has recommendations for code packaging and naming conventions.

The OVM has won recognition from ''[[Electronic Design (magazine)|Electronic Design]]''<ref>[http://electronicdesign.com/article/eda/fpga-designers-see-some-of-eda-s-best-work-in-2007.aspx Electronic Design Article]</ref> and a DesignVision award from the International Engineering Consortium.<ref>[http://www.iec.org/about/020508_dv_winners.html DesignVision Award]</ref>

The OVM was co-developed by [[Mentor Graphics]] and [[Cadence Design Systems]], and they continue to guide its evolution in concert with the nine user companies of the OVM Advisory Group.<ref>[http://www.eetimes.com/showArticle.jhtml?articleID=209904287 OVM Advisory Group]</ref> The OVM is publicly supported by more than 60 partner companies<ref>[http://www.ovmworld.org/partners.php OVM Partners]</ref> offering tools, training, and services.

The OVM was standardized within [[Accellera]], which voted to make it the basis for the [[Universal Verification Methodology]] (UVM).<ref>[http://www.accellera.org/activities/vip/VIP-TC_standard_effort_update_Jan_2010.pdf Relationship to the UVM]</ref> Accellera released version UVM 1.0 EA on May 17, 2010 <ref>[http://www.accellera.org/activities/vip Accellera Download]</ref>..
