注1:由于uvm_reg_block和uvm_reg均是uvm_object类,而不是uvm_component类,所以可以使用uvm_resource_db来进行设置; 2. 寄存器测试seq示例 回到顶部 2.1 register check seq示例 (1) spi_bus_base_seq中的get_full_name属于uvm_object内的get_full_name,uvm_sequence_item中进行了get_full_name的override; 回...

这样一来uvm_reg的predict行为就跟寄存器模型中的读写行为脱钩了,只是跟monitor上的行为想关联,即使不是寄存器模型发起的读写(例如通过一般的sequence发起的总线读写),也是可以实时的更新寄存器模型中的镜像值和期望值,这样做更能保证寄存器模型中的值与DUT中的寄存器值最大程度的保持一致。 方式3:reg_model被动实例化...

(1.1) FRONTDOOR write操作最终会转换为uvm_reg_map的do_write任务; (1.2) uvm_reg_map的do_write任务会查看系统是否设置了adapter,如果没有设置,就直接启动sequence, 让sequencer发送uvm_reg_item类型的transaction;如果设置了,那就调用do_bus_write任务. ...
