req is of the typemy_data. The`uvm_do_*macros will utilize a default in-built sequencer calledm_sequencer. If you want the sequence to be executed on some other user-defined sequencer, you have to call`uvm_do_on_*macros as shown below : ...
In one window I will write sequence diagram code and in second window you can see the 24 00:02:00,659 --> 00:02:04,579 sequence diagram generated out of this particular code 25 00:02:04,579 --> 00:02:08,199 Now PlantUML is very simple to learn 26 00:02:08,199 --> 00:02...
Every class item derived fromuvm_objectwill have aprinterinstance within it. So, a data class derived fromuvm_sequence_itemoruvm_componentwill have access to theprint()function as well. The major advantage UVM provides are the`uvm_field_*macros that automates the process of writing special pri...
UVM支持覆盖驱动的验证(CDV, Coverage-Driven Verification),即可以按照特定规则(如随机化)生成Sequence,不断提高验证的覆盖率(指设计中各个部分被调用以进行验证各个规范内定义的行为)。 图9 一个简单的UVM 框架示例 更进一步的UVM整体框架介绍在博客园用户没落骑士的这篇文章中有稍微详细一点的介绍,UVM内部各个模块...
Command line processor, to give access to command line arguments UVM 1.2 was released in June 2014 and has completed a period of public review. UVM 1.2 is somewhat controversial in that the experts disagree as to whether some of the new features introduced in UVM 1.2 represent a step forward...

Most Aldec transactors provide an additional UVM layer, which contains UVM AGENT and PROXY components. These translate UVM sequences into a transactor's API functions. Thanks to this layer, transactors can be easily connected to a UVM testbench during emulation. This makes the testing process mu...
The following keywords are characteristic: class, extends, uvm_component_utils, function, config, master, virtual, string name and extern. The file name master_drv.sv or write_xtn.sv is typical for these files. Files like these are about master, agent, environment, sequence, virtual, slave,...
