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...
To access these design registers, UVM RAL provides ready-made base classes and APIs. Some of the RAL model features are: Just like design, it supports different register attributes like R/W, RO, WO, W1C, etc. Supports two different paths for register access, frontdoor and backdoor. The ...

UVM RAL: NULL pointer is dereference I am a beginner in using UVM RAL. I am trying to access by DUT Registers using UVM_BACKDOOR. I think this should not require an adapter and a predictor. I maybe wrong thinking so. Below is my code ... ...
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。

uvm_reg_model——寄存器模型（⼀） 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...
18 UVM Register Block pyuvm implements the RAL register block classes 19 UVM Register Field pyuvm implements register fields as defined in IEEE 18002. There are still few functionalities missing like atomic Backdoor access, Field byte access, and single Field access during read or write operation...
