    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 all.,
I have one query in DUT instantiation in SV testbench.
* Below is an example of position based DUT instantion
RTL_DUT (a,b,c);
* For instantion by name.,
RTL_DUT (.a(a), .b(b), .c(c));
* But what happens when instantiated as below.,
RTL_DUT ( .* );

What does only ".*" means in above typr of instantiation, please let me know.

In reply to iamyash1234:

See section 23.3.2.4 Connecting module instances using wildcard named port connections ( .*) in the IEEE 1800-2017 SystemVerilog LRM.
