合理的使用宏可以大大简化我们在使用SystemVerilog编写代码的工作量,如果你不熟悉宏的使用,不仅降低写代码的效率,同时在阅读别人写的代码时也会产生诸多困惑,这里的例子将揭开`, `", `\`"这些宏中常用的符号的含义以及如何使用它们的神秘面纱。 我们还将探索UVM源代码中的一些宏,并建立编写宏的风格指南。 在我们开...
软件世界:program/endprogram, class/endclass initial和always无法被延迟执行,即在仿真一开始就同时执行,不同的initial和always在执行顺序上没有先后顺序,所有过程块并行执行。 always always由时钟驱动是时序,由非时钟驱动是组合或者锁存; 不同always语句之间是并行执行的; 不可初始化变量,但可以进行复位; initial 只...

Sometimes, it is useful to create a class without intending to create any objects of the class. The class exists simply as a base class from which other classes can be derived. In SystemVerilog this is called an abstract class and is declared by using the word virtual: virtual class Regist...
This example shows how to generate SystemVerilog HDL code for MATLAB® function. SystemVerilog code has more advanced features over that Verilog® code, such as the use of array ports, package declarations, structure ports and more.Examine Algorithm and Test Bench This example uses a small ...
技术标签: SystemVerilog assert简单的立即断言 测试平台的过程代码可以检查待测信号的设计值和测试平台的信号值,并且在存在问题的时候采取相应的行动。 断言里面的逻辑条件跟if语句里面的比较条件是相反的。设计者应该期望括号内的表达式为真,否则输出一个错误。 bus.cb.request <= 1; repeat(2) @bus.cb; a1: ...
