sequence,然后在最后会调用seq.start(this)启动它。这就完成了UVM default sequence的启动机制了。2.2...
1.上一节的例子中,sequence是在my_env的,但实际应用中,使用最多的还是通过default_sequence 的方式启动sequence。在某个component (如 my_env)的build_phase 中设置如下代码即可: virtual function void build_phase(uvm_phase phase); super.build_phase(phase); *** uvm_config_db#(uvm_object_wrapper)::se...
uvm_config_db#(uvm_object_wrapper)::set(this, "env.v_sqr.main_phase", "default_sequence", virtual_sequence::type_id::get()); 的方法set default_sequence,还可以用与1370行对应的代码的另一种方法(直接set virtual_sequence的实例): virtual_sequence myseq = new("myseq"); uvm_config_db #(...
UVM_ALL_ON和UVM_DEFAULT的区别 UVM_ALL_ON和UVM_DEFAULT的区别
发送sequence有两种方式。看起来都可行。但是有些UVM范例中不推荐通过配置default_sequence的方式发送。 简单来说: 通常,希望所有的激励生成和响应(即序列)在测试的run_phase()期间配置/启动。这是为了允许用户控制这些序列之间的确切关系。 使用default_sequence不符合这一点有几个原因: ...
class dpcfg extends uvm_object; rand int num_lanes; function new(string name=""); super.new(name); endfunction function void do_print(uvm_printer printer); printer.print_string("dpcfg", "dpcfg"); printer.print_field("num_lanes", num_lanes, $bits(num_lanes)); end...
(uvm_object_wrapper)::set(this,“sr1.run_phase”,“default_sequence”,seq_1::type_id::get()); But as i’m trying to start that in its main_phase, it gets terminated shortly. (uvm_object_wrapper)::set(this,“sr1.main_phase”,“default_sequence”,seq_1::type_id::get()); Here...

I am new to RAL and I am running the default uvm_reg_hw_reset_seq in my test. The test is failing for a register with non zero reset value. It is passing for others which have 0 as the reset value. I get an error as follows : "m_ral_model.xxxx_REG" value r...
