第一个uvm_build_phase::get()获得build_phase的实例,uvm_build_phase和uvm_root一样采用了单例模式,所以全局只有一个build_phase,通过 uvm_build_phaes::get()获得。所以我们平常在不同component中的 传入的phase,其实指向的都是那个唯一的uvm_build_phaes::get() 实例。其他phase也一样,实例全局唯一。 add...
在UVM中通过uvm_root的set_timeout函数可以设置超时时间: functionvoidbase_test::build_phase(uvm_phasephase);super.build_phase(phase);env=my_env::type_id::create("env",this);uvm_top.set_timeout(500ns,0);endfunction set_timeout函数有两个参数,第一个参数是要设置的时间,第二个参数表示此设置是...

默认的超时退出时间是9200s,是通过宏UVM_DEFAULT_TIMEOUT来指定的: 来源:UVM源代码 `define UVM_DEFAULT_TIMEOUT 9200s 除了可以在代码中设置超时退出时间外,还可以在命令行中设置: <sim command> +UVM_TIMEOUT=<timeout>,<overridable> 其中timeout是要设置的时间,overridable表示能否被覆盖,其值可以是YES或者NO...

一应该不用管它simv+UVM_PHASE_TRACE 可以调试 phase 超时退出机制: 1)在 test 的 build_phase 里加上 uvm_top.set_timeout(500ns,0);define UVM_DEFAULT_TIMEOUT 500ns simv +UVM_TIMEOUT=,500ns/YES限制objection的时机:推荐在sequence里的body () task中实现限制objection章节例如代码: zlass caseO ...
2. Timeout The phase ends if the timeout expires before all objections are dropped. By default, the timeout is set to 9200 seconds. You may override this viauvm_root::set_timeout. If a timeout occurs in your simulation, or if simulation never ends despite completion of your test stimul...
