某些模拟器会提供违反 SystemVerilog 严格类型规则的编译错误。例如 Aldec Riviera Pr,它可能会使用命令行参数来避免这些错误。 模拟日志 ERRORVCP2694"Assignment to enum variable from expression of different type.""testbench.sv"111FAILURE"Compile failure 1 Errors 0 Warnings Analysis time: 0[s]." 其他一些...

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。 压缩联合体(packed修饰)对联合体可以表示的数据...
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...
An array is a collection of variables, all of the same type, and accessed using the same name plus one or more indices. In C, arrays are indexed from 0 by integers, or converted to pointers. Although the whole array can be initialized, each element must be read or written separately i...
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...
