    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.

    The Verification Academy Patterns Library contains a collection of solutions to many of today's verification problems. The patterns contained in the library span across the entire domain of verification (i.e., from specification to methodology to implementation—and across multiple verification engines such as formal, simulation, and emulation).

I am using `uvm_do_wth (seq_name, {some constraints}). If the randomization fails, then there is no way to flag it. One had to manually check the log file to see if there is any constraint failure. Is there any way to resolve this issue?

In reply to jigar123:

It depends what you mean by "flag it". The `uvm_do macros emit a uvm_warning with the ID: "RNDFLD", so there are a number of ways to catch that warning.

We recommend not using the `uvm_do macros and instead inserting the exact code needed to meet your requirements.
