在SV中用来做线程间同步的几种方法,它们分别是semaphore、event和mailbox。 而在UVM中event进化成uvm_event,不仅仅拥有达成不同组件进程之间同步的功能,还能像TLM通信一样传递数据,并且作用范围更广(TLM通信只能在uvm_component之间,而uvm_event不限于此)。 常见的uvm_event使用方法 首先从常见的uvm_event达成同步的...

使用factory注册宏的时候,引入field automation机制,一般定义uvm_sequence_item类时,使用'uvm_object_utils_begin()和'uvm_object_utils_end实现factory注册,并使用'uvm_field注册所有字段,即可调用copy、compare、print等函数。 注意构建函数new()的声明方式,uvm_component相关类的new函数有string name(实例名字)和 uvm...
In case of UVM, Transaction Level Modelling is used which supports multiple languages and it supports port to port connection, unlike Mailbox which has component to component connection. Thus, there are many advantages of using UVM for verification purposes. Up next, we will see how UVM based ...
考虑到层次化;下图的连接如果用mailbox,那么 agnet.monitor.mb = sub.scoreboard.mb, 垮了很多层次,如果在sub里添加了一个agent环境,那么就要改写成sub.agent.scoreboard.mb。 如果用TLM端口连接,则只需要agent.ap.connect(sub.exp) 。跨层次可以一层层的连接。跨层次会带来很多编译的问题。
[299] 用户调用sequence.print()方法时,将调用sequence中的哪个方法? [300] 找出UVM sequence的以下代码部分中的所有潜在问题 代码语言:javascript 复制 taskbody();seq_item_c req;start_item(req);#10ns;assert(req.randomize());finish_item(req);endtask ...
“uvm_cmdline_processor” has various in-built methods like get_args(), get_plusargs(), get_uvm_args() and get_arg_matches() to retrieve command line arguments. The “get_arg_values” can be used to retrieve the suffix values of an argument. Based on any given scenario needed, the re...
