    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.

How do access memory model methods from sequence?

UVM MEMORY MODELING 5 Resource_db 5

I modeled an AXI slave memory as an object with methods for reading/writing. How can I access these methods from a sequence for preloading, data checking, etc? I tried putting the memory handle into the uvm_config_db/uvm_resource_db and getting from the sequence without success. Is this possible? If the resource_db is the proper way, how exactly do I set/get? Is there a better way to model a slave memory so I can access from both components and sequences? Thanks in advance, Steve

Yes this solution is possible. From the sequence side you need to get a handle to your config object. Best way is to have your sequencer retrieve the object handle once from config DB, and then provide it as an API for each sequence to get a local handle and call methods or access the data.
There are different ways for the sequence to get this access. See Configuring Sequences in the cookbook for examples.
