    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.

Hello

i have a class with random variable which can range between [1:100]
I have a test-case which when I simulate with seed = 1 randomizes my class properties twice (meaning generating 2 random values for the variable).
Now if I run the same test with seed = 2/3/any does the new seed randomize my class properties exactly twice or can that vary (can generate more/less random variables)?
I wanted to know if this randomization is test specific or seed specific

In reply to Rfed:

You would have to show your code before anyone can provide a specific answer.

How is the number of randomizations determined? Does your code loop a specific number of times? Or is the loop iteration count randomized? This will control the number of random values generated.
