    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.

I have an 8-bit register with 2 different bit-field.
______________________
| 7 : 4 | 3 : 0 |
| ENA_2 | ENA_1 |
|___________|__________|

I need a mechanism where I can update only one field at a time without modifying the value of others, how can I achieve this?

In reply to nid_8486:

How are you accessing the register? Are you using the UVM RAL?

The simplest solution is to read the register, update the desired bits, and then write the register.
