Uvm_deprecated

[chenyong]

Hi,

when I try to run with uvm-1.1 to set default sequence, I always get this:

UVM_WARNING /apps/INCISIV102/10.20.029/tools/uvm-1.1/uvm_lib/uvm_sv//src/seq/uvm_sequencer_base.svh(1411) @ 0: uvm_test_top.tb0.timer3_rx_env.agent.sequencer [uVM_DEPRECATED] Registering sequence 'uvm_random_sequence' with sequencer 'uvm_test_top.tb0.timer3_rx_env.agent.sequencer' is deprecated.

See documentation for uvm_sequencer_base::start_phase_sequence().

Can anybody help me to understand why there are "deprecated"? I must apologize I can't find any clue from documentation for uvm_sequencer_base::start_phase_sequence() in the uvm_sequencer_base.svh. Does uvm-1.1 has a big difference from uvm-1.0ea? thanks.

hi,

this is the result of using the old style 'uvm_sequence_utils' macro. see for instance

Thanks uwe. The document is helpful. I noticed there is uvm-1.1 now. Is there any document on migration from 1.0 to 1.1? thanks.
