    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.

If the tool provide us with state and transition coverage of a finite state machine. What is functional coverage of a state machine than? What else is left for their to cover in a state machine? As tool give us the coverage of every state and state transition?

In reply to Rana Adeel Ahmad:

FSM coverage is not functional coverage. It is closer to code coverage in that can help identify what has not been tested or code that is unnecessary.

The only exception to this is if the sate of the machine is being used to communicate with another machine that is outside the design.
