我们在sequence中往driver发包时,最常用的方法就是使用uvm_do()系列宏,偶尔会使用方法start_item()和finish_item()的组合,极个别场景下会 使用`uvm_create()和`uvm_send()宏,极极个别场景下还会看到create_item()方法的使用,这些宏和方法有什么区别,各自使用场景有什么局限和注意事项,他们分别定义在了UVM源代码...
Hi, I am new to UVM. Can anyone help me in making sequence from this task which was in interface of my sv code. task automatic reg_read_lane (input [`NB_LANES-1:0] lane, input [ADDR_WIDTH -1:0] addr, output [DATA_WI…
I've got following code I want to execute the query first and then return result. How should I do it. I've also done it with simple for loop but does not work. I think you just need to call next() aft... what is the difference between \c and \\c?
UVM中启动sequence方法总结 , CONSTRAINS)。通过default_sequence启动: 方法是:在test_case中的build_phase中,通过uvm_config_db#(uvm...启动sequence,比如uvm_test类或其衍生类,即测试向量 ) set的第一个参数和第二个参数构成了sequencer的路径。由于除了main_phase外,还存在其它任务phase,如 ...
pre_bodyandpost_bodymethods are not invoked in a`uvm_domacro call. The`uvm_domacro will allocate an object of typemy_datatopkt, randomize it and send it to the default sequencer associated to execute this sequence. Use of this macro simply reduces the code required to achieve the objective...
第二,需要几个不同的sequence就写几个sequence,sequence之间没有联系,继承于uvm_sequence; 第三,在每个具体的执行case下,可以用asserte插入具体的配置参数,并且每个case设置自己独立的default_sequence; 第四,在终端指定不同的case_name跑不同的case; 下面给出具体的参考代码… ...
To retain the parameter value in the SystemVerilog environment use a Simulink.Parameter. In that parameter, the default value is 2100 and the valid range is [0, 4936]. (The pulse must be entirely within the frame of 5000 samples.) In the generated UVM code, two constraints are placed on...
版本兼容地启动sequence uvm从1.1d到1.2再到IEEE1800.2,有了很多变化。尤其是从1.1d到1.2,在objection的使用上有了一些关键性变化。 在uvm进入到1.2后,starting_phase不在推荐使用。更为重要的是,不仅仅是不再推荐,而且如果以default se
