    The Verification Academy offers users multiple entry points to find the information they need. One of these entry points is through Topic collections. These topics are industry standards that all design and verification engineers should recognize. While we continue to add new topics, users are encourage to further refine collection information to meet their specific interests.

    The Verification Academy is organized into a collection of free online courses, focusing on various key aspects of advanced functional verification. Each course consists of multiple sessions—allowing the participant to pick and choose specific topics of interest, as well as revisit any specific topics for future reference. After completing a specific course, the participant should be armed with enough knowledge to then understand the necessary steps required for maturing their own organization’s skills and infrastructure on the specific topic of interest. The Verification Academy will provide you with a unique opportunity to develop an understanding of how to mature your organization’s processes so that you can then reap the benefits that advanced functional verification offers.

Hi,

i am wondering why do we need to extend virtual interface wrapper from ovm object, is it that since interface type doesnt match with any ovm class hierarchy we extend it only from ovm_object?

please let me know.

Thanks
Pradeep

In reply to Pradeepkumar:
Because the wrapper is an object that you pass using the configuration database with set_config_object and get_config_object. And that object has to be derived from ovm_object.

Once you move to the UVM, there is no longer a need for config wrappers.
