通过python实现一个简易的reg_model

        register model 在uvm的验证环境里是必不可缺少的一部分，涉及到对dut的寄存器的操作都需要通过register model。register model不同与uvm 其它component，它比较独立。register model里涉及到了一些概念，uvm_filed,uvm_reg,uvm_block。这三者具有层层包含的关系，最终生成一个完整的register_model。如果同过手动的方式去写register_model,对于变动比较的小register_model简单改下就行，但是对于变化比较大的register model就会花费大量时间，考虑到register model的生成是具有一定规律的，因此可以考虑通过python去生成，通过制定一些规则给DE，让DE按规填写excel 表格，然后DV可以根据表格可以生成需要的registermodel
