uvm_mem_access_seq For each location of the memory, writes via frontdoor and checks the if the value is set correctly via backdoor. Then, do the reverse operation where write happens via backdoor and verification occurs through frontdoor. uvm_reg_shared_access_seq Writes all the registe...
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...

uvm_reg_block是最顶层的层次结构,通常,uvm_reg_block具有所有寄存器(uvm_reg)的一个实例,或者可能具有其他uvm_reg_block的实例。 uvm_reg模拟设计内部的寄存器。根据其定义,每个寄存器可以具有一个或多个uvm_reg_field。 uvm_reg_field代表寄存器的域。
