Structure可以包含不同数据类型的元素,这些元素可以作为一个整体引用,也可以通过其名称单独引用。这些元素具有相同数据类型的数组完全不同。 // Normal arrays -> a collection of variables of same data typeintarray [10];// all elements are of int typebit[7:0] mem [256];// all elements are of bit...

In the examples above, we're declaring variables of different Verilog and SystemVerilog integer data types. Theshortintvariablecountis assigned a value of-32768, which is the minimum value that can be stored in ashortint. Theintvariablenumis assigned a value of10. ThelongintvariablebigNumis assi...
Verilog allows you to make procedural assignments to variables (and synthesis tools may further limit where you can make procedural assignments to variables) A variable behaves like a variable in any other programming language: you make an assignment to that variable, and the value o...
SystemVerilog有三种类型的联合体:非压缩联合体、压缩联合体和标签联合体,大多数综合编译器只支持压缩联合体(Vivado综合支持非压缩联合体),因此最佳的做法是在RTL设计中仅使用压缩联合体。非压缩的联合体和标签联合体体可用于建模测试台和高级抽象模型,但不应用于RTL建模。
SystemVerilog允许参数化数据类型。这是根据模块中的参数定义数据类型,以便通过在实例化模块时更改参数值来将不同的数据类型用于模块。 module my_mod #(parameter type my_param = int) (//inputs and outputs); my_param my_sig; //this declares a signal called my_sig that is of type int ... end...
FPGA-in-the-Loop IP Core Generation Structuresstruct Arrays of structures are not supported as input or output for HDL code generation. HLS code generation supports arrays of structures as local variables in the MATLAB functions. For the IP Core Generation workflow, structures are supported...

This chapter describes the rich set of data types that SystemVerilog offers. Integer datatypes and real datatypes are discussed. In addition, use-defined types; static, local, automatic, and global variables; enumerated types; string data types; and event data types are discussed. Each data type...
