1)这个芯片的virtual sequencer 中,应该包含A,D,F 的sequencer。同一推荐在base_test 中例化virtual sequencer。在芯片级别建立自己的virtual sequencer。 3.virtual sequence 都使用uvm_declare_p_sequencer 宏指定sequencer。这些sequencer 在模块级别存在,但是在芯片级别根本不存在,所以这些virtual sequence 无法用于芯片级...
本文通过工作过程中使用virtual_sequence和virtual_sequencer时遇到的一个bug，引申出了UVM源代码中`uvm_de...
下面例子中,向virtual sequencer中传递sequencer句柄的方式有两种,一种直接通过层次化引用传递;另一种通过config_db机制。 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 class simple_tb extends uvm_env; cpu_env_c cpu0; // Reuse a cpu verification component....
总结一下:对于virtual function ,是在base中提供了一个函数模板,但不是必须进行override,但对于pure virtual function 而言,必须进行override,如果你忘记override,则会出现编译错误,也起了一种提示作用。 virtual sequence/sequencer 之前的文章讲过,就不再赘述,可以参照链接。 参考:我眼中的UVM |08.virtual_sequece和v...
function new (string name = "my_virtual_sequencer", uvm_component parent); super.new (name, parent); endfunction // Declare handles to other sequencers here apb_sequencer m_apb_seqr; reg_sequencer m_reg_seqr; wb_sequencer m_wb_seqr; ...
`uvm_declare_p_sequencer (my_virtual_sequencer) function new (string name = "my_virtual_seq"); super.new (name); endfunction apb_rd_wr_seq m_apb_rd_wr_seq; wb_reset_seq m_wb_reset_seq; pcie_gen_seq m_pcie_gen_seq; task pre_body(); ...
m_v_sqr = virtual_sequencer::type_id::create("m_v_sqr", this); endfunction: build_phase // Connect - where the virtual_sequencer is hooked up: // Note that these references are constant in the context of this env function void connect_phase( uvm_phase phase ); ...
第九段:Virtual_sequencer的调用 1)基础用法:在virtual_sequencer中将各个env的sequencer包括进来,同时base_test在connect_phase中将各个env放入指针中,在case在main_phase中设置default_sequence,让其进入phase时自启动。 平常的uvm的object的控制放到sequence的body中实现,引入virtual sequencer后,则将其放入顶层的......
(virtualsequence),不需要sequencer就可以传递sequenceitem。相反,通过sequencer的句柄,可以控制其他sequences的运行。uvm_top提供了一... items的顺序我们希望有另一个模块来负责,同时tester也将改名为sequencer,仅仅实现sequenceitems的传递功能。sequencer从sequence中取出一系列的 ...
