另外一点,NO_REG_TESTS和NO_REG_HW_RESET_TEST区别在于前者针对所有的内建sequence都排除,而NO_REG_HW_RESET_TEST仅仅针对的是uvm_reg_hw_reset_seq这一单一sequence,又比如uvm_reg_bit_bash_seq使用的是NO_REG_BIT_BASH_TEST 由于内建sequence的启动是可以出现在任意task phase的任何地方的,所以我们只需要在执...
而uvm_reg_bit_bash_seq中会嵌套的调用子sequence uvm_reg_single_bit_bash_seq,这会导致uvm_reg_single_bit_bash_seq中的response_queue出现overflow的情况,也就是log中报出来的层次[bitbash_seq.reg_single_bit_bash_seq]。 图9 仿真结果 进一步分析我们发现uvm_reg_bit_bash_seq中定义的uvm_reg_single_bit...
下面的例码分别添加了uvm_reg_hw_reset_seq、uvm_reg_bit_bash_seq...)和寄存器的验证。在早期时,寄存器模型的验证可以为后期各个功能点验证打下良好的基础。比如,通过内建的寄存器或者存储序列可以实现完善的寄存器复位值检查,又比如检查读写寄存器的读写功能是否正常等。 不过有...
uvm自建的针对reg的sequence,针对普通的reg有:reg_access_seq,reg_bit_bash_seq,reg_hw_reset_seq。 uvm_reg model,主要实现了 1) 增加了对dut的reg进行访问的方式,可以直接通过reg model进行访问。传统的只能是通过sequence,启动在bus的sequencer上来实现。 2) 方便了对dut reg进行测试的方法,通过build-in sequ...
