// in-between events such as marking the begining of the address and data // phases of transaction execution could be implemented via the // <events> pool. 概括的讲,就是说uvm_transaction这个类中主要提供了一些记录transaction相关时间戳的功能,在uvm_sequence中调用相关宏或者方法时会自动调用相关时间...
3.The full_inst_path is matched against the contentation of {parent_inst_path, “.”, name} provided in future create requests. 4. When the factory processes instance overrides, the instance queue is processed in order of override registrations, and the first override match prevails. Thus, m...

验基于 UVM Phases 的数字 IC 复位验证张启晨(无锡中感微电子股份有限公司)摘要:数字 IC 设计验证过程中,确保数字 IC 设计在上电后(Power-On)或出现错误后能通过复位进入一个的确定的初始状态,是设计功能正确实现的基础。验证人员需要编写测试用例,以验证各种不同场景下复位后设计的正确性和可靠性,复位验证是验证...
UVM基础之---uvm phases机制 UVM基础之---uvm phases机制 代码的书写顺序会影响代码的实现,在不同的时间做不同的事情,这是UVM phase的设计哲学,UVM phase提供了一个通用的TB phase 解决方案。支持显示的隐式的同步方案,运行时刻的线程控制和跳转。只要把代码填入对应的phase,这些代码就会自动执行。phase 的引入...
UVM components use the phasing mechanism to perform initialization and configuration tasks in a specific order. Phases allow components to construct their internal hierarchy, connect to other components, and finalize their configurations before the actual test starts. This ensures a well-structured setup...
“run” phases (times) are sorted by time and then executed in order of// occurrence for settings of the same time. For example:///| +uvm_set_verbosity=uvm_test_top.env0.agent1.,ALL,UVM_FULL,time,800/// Variable: +uvm_set_action/// ~+uvm_set_action=<comp>,<id>,<severity...
Below block diagram shows the order in which the methods will get called on calling the start of a sequence. uvm sequence phases * mid_do and post_do are functions, All other are tasks Starting The Sequence: Logic to generate and send the sequence_item will be written inside the body(...
Settings for “run” phases (times) are sorted by time and then executed in order of occurrence for settings of the same time. For example: <sim command> +uvm_set_verbosity=uvm_test_top.env0.agent1.*,_ALL_,UVM_FULL,time,800+uvm_set_action +uvm_set_action=<comp>,<id>,<severity>...
uvm_phase的静态成员m_run_phases的实现如下: Caption 上⾯的m_phase_hopper是⼀个uvm_phase类型的mailbox,在m_run_phases中,先是将common domain的第⼀个phase(即 build_phase) put进mailbox中,然后进⼊forever,在forever中不断地去get phase,get成功就去执⾏phase的execute_phase task。 在uvm_phase...
