Unable to call a task using a sequence handle present inside another sequence

[zafar0070]

Hi All

I am facing a problem while accessing a task which is present inside a sequence.

Scenario:

1. I am creating the handle of a sequence seq_1( which has a task defined say suppose task_1) inside body of another sequence say suppose seq_2.

2. Inside the body of sequence seq_2 did create for seq_1.

3. Trying to access task_1 by using "seq_1.task_1" inside the body of seq_2.

The task_1 is not invoked at all as the functionality performed by task_1 is not getting executed.

Can anyone tell me the reason?

Thanks and Regards

Yes, i m facing this problem too.

Can someone help?

This sequence where the task is present is extended from uvm_reg_sequence.

Hi,

Issue is with the create method of seq_1 inside seq_2. I have other idea which might helpful to you.

i) Define a parent sequence and define a task inside it say;

class parent_seq extends uvm_sequence#(seq_item);

......define task here.........

endclass

ii) Define a child sequence extends from parent sequence and call the parent task inside it say ;

class child_seq extends parent_sequence;

super.disp();//disp() is the task present in parent sequence

endclass

Thanks,

Mahee.

Thanks Mahesh !!

Conclusion : we cannot instantiate other vseq to use the task. only possible is to create the vseq with extend from the vseq where task is defined.
