    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.

  1. Re: How to use try_next_item

    Posted by kurts on Jul 6, 2011
    Hi, try_next_item is a task, which means it does not return a value, so you cannot use it in an "if" statement like that. If there is no item ready, then try_next_item will set its argument to null, so you should check the argument instead. Some ...

  3. Re: Why to include ovm_macros.svh?

    Posted by kurts on Jul 6, 2011
    Hi, Macros are processed by the preprocessor, which runs before any compilation takes place. Macro definitions are not "stored" in a package, so they have to be processed each time you compile. By the time the compiler runs (e.g. to do the impor ...

  4. Re: Using virtual class interface for fifos

    Posted by kurts on Jul 6, 2011
    Hi, If I am guessing correctly what you are trying to do, you are filling a fifo with objects of either class1 or class2 type. When you get objects out of the fifo, the fifo just gives you a base_class object. Instead of class1'(obj) and class2' ...

  7. Re: Is "assign_vi" the only way to pass interface to the components from environment??

    Posted by kurts on Jul 6, 2011
    The assign_vi method is absolutely not the only way to do this! It is the scheme that the xbus example uses, so unfortunately I think people assume that is the "official" method. There are definitely better ways to get the real interface connect ...

  8. Re: error: expecting a task

    Posted by kurts on Jul 6, 2011
    What you declared is a special kind of export called an "implementation", or "imp". You need to supply the interface functions (in this case the "put" task) in an object of type hst_tx_monitor, and pass a handle to that objec ...

  9. Re: Use of set_config to pass object to class and its child

    Posted by kurts on Jul 6, 2011
    Hi Tushar, If you want to set a config value for the driver and all its children in just one call, you can use set_config_object("driver_obj*","config_obj",my_object,0); Note that the path string does not have a dot "." chara ...

    Hi George, I think that a couple of reasons why you would use the config facility, even for direct children, is that- It is a good habit to design with the future in mind, and always keep your options open. In other words, the driver might not always be a ...
