2.如果design的transaction有 outstanding,那么uvm_tlm_fifo就直接可以model design的fifo行为了(当然用queue做也不错,甚至碰到out of order的时候比fifo还好用)。 3.通过imp加后缀可以解决多对port,export的情况,但如果port数据多了呢。比如一个有16进16出的AXI interconnect,在scoreboard的port上去申明16个不同名字...

All signals coming out of the sequence must be connected to the driver, predictor, or the scoreboard. Other output signals are ignored for UVM generation. If your model includes a driver subsystem, then all signals coming out of the driver must be connected to the DUT. ...
其实在上面的代码中能够看到,build_phase中scoreboard执行是要先于wr_agent的,这是因为uvm中字典序所导致的。scoreboard的s在字典序中要先于w,如果将scoreboard的例化名称改为z_scoreboard,则会晚于wr_agent执行。实际使用中这种顺序理论上不应该产生影响,但是假如要求一定是某种固定的执行顺序,那么这种代码存在很高风险...
Next is the Clean Up phase. Everything starting from extraction, reporting to final category belongs to this class. As part of extraction, we basically gather all the information that was collected by Scoreboards and Monitors. Next, we compare the results obtained from the Actual DUT and Refere...
