Passing sequence_items from v-sequence to sub-sequence?

[TonyJ]

Is there a way for a virtual sequence to pass a sequence_item (that it has already created) to a sub-sequence, say for instance to an agent sequence, without using a TLM?

 

I really would like to avoid adding a TLM to the agents sequencer if I can avoid it.

The sub-sequence would be invoked from the v-sequence by calling start().

The sequence_item is a potentially largish data structure so using the `uvm_do_on_with macro is a bit unwieldy.

 

I think I see a sneeky way to do it by using the parents mid_do() method, but haven't tried it yet and wondering if there's a more direct way I'm not seeing.

 

Thanks in advance.

Just use `uvm_create instead of `uvm_do. Create will create the sequence for you. Then you can assign the data structure--or anything else--to the sequence you've created. You can further randomize the sequence or perform any other manipulations you wish before calling `uvm_send on it.

 

For example:

my_seq_c my_seq;
`uvm_create(my_seq)
my_seq.data = my_big_ol_data_array;
`uvm_rand_send(my_seq)

DUH!

was thinking too hard. Couldn't see the forest through the trees.

 

Thanks!!
