passing sequence name on command line at run time

[amitrana]

Hi UVM,

IN uvm we pass the name of test at run time with +UVM_TEST_NAME .

Can we do the same with the parameterized seqence,passing their name on command line by using the $value$plusargs.

Second can we run a parameterized test in uvm?

You can, but not directly. When you register a parameterized class with the factory using the the `uvm_object_param_utils macro, it does not register a string name with the factory, only by type. Therefore you can only create or override these classes by type. I see two possible options:

• You create your own string mappings using an associate array.

  uvm_object_wrapper type_lookup_by_string[string];type_lookup_by_string = '{"myseq1_4":myseq#(1,4)::get_type(),                                        "myseq2_8":myseq#(2,8)::get_type()};...factory.create_object_by_type(type_lookup_by_string["myseq2_8"],...);

• You register the class with the factory using the uvm_object_registry class and provide a string mapping there. See the probe class in my DVCon paper.

  class myseq #(int A, extends uvm_sequence;typedef uvm_object_registry #(myseq#(A,),$sformatf("myseq%0d_%0d",A,) type_id;...factory.create_object_by_name("myseq2_8",...);

Hi Dave,

Thanks for such a beautiful reply.

Hi, Was this possible? can you show me how you did this? I wanted to pass a sequence name through command line, to be used in a sequence called by my test
