32、sequence如何才能独占访问sequencer? 33、流水线和非流水线sequence-driver模式有什么区别? 34、我们如何确保在driver驱动多个sequences 时,则driver的响应会发送给正确的sequences ? 35、什么是m_sequencer句柄? 36、什么是p_sequencer句柄,与m_sequencer相比有什么不同?
5. 只有使用default_sequence的方式启动,case0_sequence中starting_phase才不等于 null. (只摘取了与策略模式有关的 code)+: default_sequence的方式启动,会调用seq.start()函数来运行body()函数的代码, 不同用例body()函数的实现不同,这里的body()就相当于策略模式中的“算法",将body()函数的实现放在子类sequen...
uvm_transaction继承自uvm_object,添加了timing和recording接口,该类是uvm_sequence_item的基类。下边将做剖析 1. 这个类提供了时间戳属性(timestamp properties),通知事件(notification events),和交易记录(transaction recording)支持。 2. 使用这个类作为用户定义的基础交易是弃用。其子类uvm_sequence_item应当作为基类为...
