4 union 联合类型的语法: typedef union packed { struct packed { logic zero; logic [31:0] aluout; } alu; struct packed { logic branch_taken; logic [31:0] pcbranch; } branch; struct packed { logic [31:0] addr; logic mem_read; } memory; } result_t; result_t res; logic [31:0...
typedef关键字用于为数据类型定义一个新的名称。 下面是一个使用__packed和typedef的示例代码: typedef __Packed struct { char c; double d; char e; } Packed_S; 则该结构体将只占用10个字节。 如果定义: __packed关键字的意思是在struct和union结构中不添加填充字节: struct S { char c; double d; c...

typedef struct packed { bit [3:0] s1; bit s2; } myStruct; typedef union { logic [7:0] u1; myStruct b2; } mUnionT; mUnionT Union1;
typedef & struct & union typedef 创建新类型 typedef bit[31:0] uint; 自定义类型后缀常带"_t" struct 只是数据的集合所以是可综合的 默认情况下,结构体是非压缩的(unpacked),结构体成员是独立的变量或常量 压缩(packed)结构体按照指定的顺序以相邻的位来存储结构体成员;压缩结构体被当做一个向量存储,结构体...
That is then in a union so I can also address it as an array and show the various values on a display in text, using a for loop. I don’t yet see how accessing it as -> will make anything any more readable. I could also define it using Typedef, but, apart from a little less...
Defines a union type of all the values stored in TObj.interface User { id: number; login: string | null; password: string; isDisabled: boolean; } /* number | string | null | boolean */ type t0 = ValueOf<User>; /* union type of all properties and methods of `Array<boolean>` *...
