    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,
In Coverage can we have same signal assigned to different coverpoints,
please correct me if am wrong.

for example

covergroup cg;
	option.per_instance = 1;
data_1 : coverpoint datain{
         bins small = {0:50};
}
 
data_2: coverpoint datain{
         bins high = {100:200};
}
 
endgroup

In reply to rohit_kumar:
Correct, as long as you have given them two different coverpoint labels. In this particular case, the total coverage would be the same as if you had only one coverpoint with two bins.

Hai dave,

suppose if we have to write and read two individual signals then I need to cover four possible combinates of wr and rd.

how to write coverage on it ?

Not sure how your question relates to this thread. Perhaps you should start a new question explaining exactly what values need to be covered.
