Array[2][3][2][2] = xxxx; 1. 的时候,到底是对哪个位置赋值了?? 话不多说,直接看解答好啦~最后的答案其实很简单,因为有一个简单的图示估计很多人知道,就是逆时针索引法: 合并数组和非合并数组的选择 合并数组:和标量进行相互转换,等待数组中的变化必须使用合并数组 动态数组 sv提供动态数组,动态数组在声...

Read more onSystemVerilog Array Manipulation. Give an example of a function call inside a constraint. The function must return a value that can be used in the constraint expression. Here's an example: functionintrand_range(inta,b);return(a+b)%2;endfunctionclassABC;randbitmy_val;constraintmy...
SystemVerilog在基本数据类型的基础上,引入C/C++语言中构造类型的概念,设计了数组(array)、自定义(typedef)、枚举(enum)、结构体(struct)和联合体(union)等灵活多样的数据类型,以满足不同抽象层次的建模。 1.数组(array) 在VerilogHDL中学习了数组类型的定义及赋值,如“reg[7:0]mem[1:256];”。Verilog中对数组...
