SystemVerilog是一种硬件描述语言,被广泛应用于数字电路的设计与实现。作为一种描述数字电路行为和结构的工具,其核心在于运算是操作变量和表达式的工具。本文将详细介绍SystemVerilog中的一些常见运算符及其用途。 一、算术运算符 算术运算符主要用于进行数值计算。以下是SystemVerilog中常见的算术运算符及其用途: 加法(+):...
system verilog 逻辑运算符返回值 在SystemVerilog 中,逻辑运算符(logical operators)用于对布尔值进行操作。它们返回一个布尔值,表示操作结果。 常用的逻辑运算符包括: 1. 逻辑与(AND):如果两个操作数都为真,则返回真;否则,返回假。 2. 逻辑或(OR):如果两个操作数至少有一个为真,则返回真;否则,返回假。 3...

14. What is the procedure to assign elements in an array in systemverilog? Ans: Assigning arrays in systemverilog uses the replicate operators. Eg: int n[1:2][1:3]={{0,1,2),{3{4}}}; 15. What are the types of arrays in systemverilog? Ans: There are two terminologies associated...
Verilog 最常用的 2 种数据类型就是线网(wire)与寄存器(reg),其余类型可以理解为这两种数据类型的扩展或辅助。 一、线网(wire)wire 类型表示硬件单元之间的物理连线,由其连接的器… 耐心的小黑发表于Veril... 芯片设计:Verilog之常见的位宽不匹配错误 FPGA自习室 利用sv2v,将system verilog语言转化为verilog语...
SystemVerilog Strings What is a SystemVerilog string ? 数据类型是有序的字符集合。变量的长度是集合中的字符数,这些字符数可以具有动态长度,并且在模拟过程中会发生变化。字符串变量表示字符串的方式与字符串文本不同。使用变量时不会发生截断。string

Design data often has logical groups of signals, such as all the control signals for a bus protocol, or all the signals used within a state controller. The Verilog language does not have a convenient mechanism for collecting common signals into a group. Instead, designers must use ad-hoc gro...
