As part of the kick-starting of the Open Virtual Platform initiative in March 2008, Imperas made the OVPsim simulator available under Windows XP for free to all users. This allowed OVP to get a lot of feedback from companies, universities, and individuals.
In April 2009, OVP commissioned a survey of its over 1,000 registered users that had downloaded almost 20,000 items, to help guide its future, especially asking questions about how to support Linux etc.
More than half of the respondents indicated that OVPsim was an excellent tool and that it should be maintained and supported - on Windows and Linux. Almost all of the respondents rated the open source nature of the OVP models as an important factor in the OVP interest, adoption, and success.
In May 2009 the OVP licensing of OVPsim changed. OVPsim is now available on Windows and Linux, and is available for free only for non-commercial use. Commercial users can use the free download for evaluation etc., but can only use OVPsim for commercial use by obtaining a commercial use license from Imperas.
The fee that Imperas charge for the commercial use of OVPsim covers maintenance, support and enhancements. This enables OVPsim to evolve, and for OVP to evolve and provide more free open source models to the Virtual Platform community.
Users that downloaded an OVPsim version upto version 20090319.0 can use it under the conditions of the then license (installed as part of the installer) and only need to move to new versions (covered by the new license terms) for updates, new features etc.
To read the OVPsim licensing terms relating to the current downloadable version, please see the section above and the FAQ at the bottom of this page.
In a recent survey of OVP users, over 60% of the respondents valued the open source nature of the OVP models as most important to them. We are committed to developing and providing more models as open source.

The terms of the click through OVPsim license specify that evaluation is OK, but commercial use requires a commercial license.
If you violate the terms of the click through license agreement, or do not inform Imperas of your change of usage, or you do not provide enough information to ascertain your intended usage of OVPsim, then we reserve the right to disable your access to OVPworld.org, and stop providing you with license keys - until the situation is resolved.
Please just keep us informed of your usage.
