UVM Factory override and compilation issue

[grai]

Dear All,

I have an env that I am factory overriding with a new env called new_env. In new_env I have an agent called agent that doesn’t exist in env and is only instanced in new_env. In my test, that overrides env with new_env, I want to start a sequence on agent. Since new_env doesn't exist from the compilers point of view until the build_phase() (runtime) is done, the compiler errors due to the agent not existing.

How do I inform the compiler that new_env will exist once we're in runtime?

Thanks!

If you use the following way to configure your agent in new_env to run your_seq, it should not fail.

uvm_config_db#(uvm_object_wrapper)::set(this,
   “new_env.agent.sqr.main_phaseâ€,
   “default_sequenceâ€,
   your_seq::type_id::get()
);

hi,

either

- use the config_db so your sequencer starts the sequence you want

- start the sequence manually from the appropriate phase hooks inside new_env

- $cast your env to the new_env type if its a new_env, then start the sequence

Thanks Uwe! I tried your 3rd suggestion and it worked. Excellent!
