Switching between data_items during simullation

[Ilanr]

Hi , 

 

I would like to use some data items in one test: frame_packet,  short_packet , illegal_packet.

 

In the uvm documentation i found that in order to switch between packets i should use factory setting in the test:

 

frame_packet::type_id::set_type_override(short_packet::get_type());

 

according to my understanding this completly replaces that data item and does not leave option to use frame_packet in this test.

 

Is there any other way to do it?

 

Thanks, 

Ilan

why not just write a sequence which selects one of these packets?

/uwe

 

// short skeleton, you can improve this scheme ...

class bla extends uvm_sequence;

frame_packet a;

short_packet b;

illegal_packet c;

 

rand int sel;

 

task body();

case(sel)

0: uvm_do(a);

1: uvm_do(;

2: uvm_do©;

endtask

endclass

Seems like a good solution.

 

Thanks,
