    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 am starting 1 sequence in run phase of base test which is checking activity on interface it will raise fatal error after it detects no activity till 200us. Now I am extending base test in another test and here I don't want that fatal error to come if there is no activity on interface for 200us. So it means I need to stop that sequence which is running in base test. I tried solutions from other forums like using kill() in run phase of extended test but it didn't work for me.
Yaa I need that activity detector sequence in other tests so can't completely remove from base test so I just need to somehow disable that particular sequence only in my extended test.
In my base test other sequences are also running so I can't stop all sequences of base test. I just want to stop particular sequence of base test in through extended test.
I had taken handle of sequence in base test and also created in build phase of base test.

Kindly help me in these as I am new to UVM.

Thanks in Advance

In reply to om30:

I do not believe it is agood idea to check any activity on your pinlevel interface. Instead I'd use a property checking this.
But of cause there is a solution for your for your appraoch. You can use a flag in your seq_item which will enable/disable the checking.

You can use virtual function/task. place your code where you are running sequence in one task and override it inside extended class.
