可以在UVM中自定义phase,然后插入到已有的phase之间,自定义phase继承自uvm task phase,需要实现其中的exec task和exec func方法。69、RAL backdoor和frontdoor访问有什么区别?backdoor访问:通过RTL信号路径访问,不消耗仿真时间frontdoor访问:通过数据总线协议访问,消耗仿真时间 70、set_config_*和uvm_config_db有什么不...

对于一个复杂设计,寄存器模型要能够模拟任意数量的寄存器域操作。UVM提供标准的基类库,UVM的寄存器模型来自于继承自VMM的RAL(Register Abstract Layer),现在可以先将寄存器模型进行XML建模,再通过脚本工具直接生产寄存器模型。首先来看看uvm_reg_model的代码,该文件用来保存Register Layer的全局变量和文件include。

Peek is a backdoor access method which directly accesses the simulator's database to get the DUT's register values without using simulation time. Note that only 4 registers are updated by this transaction in the figure. The 4 registers are REC_reg00∼02(denoted by rcv0∼2 in the ...
Hello once more, I am trying to implement backdoor access to registers and facing an issue when trying to use hdl_path_slice field property. While playing in the actual register RAL class definition i noticed that the following command d...
