    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.

difference between get() and get_next_item()+item_done()

hi,

I am a newbie for OVM. I read that get() call is equivalent to calling get_next_item, followed immediately by item_done.
So my question if get() does the function which get_next_item() and item_done() together do, then why there is a need for two different functions ?

Thanks

If you need to insert a delay between the two methods (get_next_item() is a task, item_done() is a function)

Thanks Dave.

But can you explain in some detail.

Thanks.

Hi Dave, Could you explain this in bit more detail, possibly with an example ?

Thanks,

Hi Dave,

Sorry, after reading the article, I can understand the two use models and how they work. However, it is still not clear where it is possible to insert the delays?

In reply to mseyunni:

With get(), the function item_done() is immediately called after the get_next_item() task, so if you want to have a delay between get_next_item() call and item_done() call, then in that case you should separately call get_next_item() and item_done().
