结构体内的组 [英] Groups inside structs

问题描述

伪代码：

  typedef struct {
 input_group {
 logic a; 
} 
 output_group {
 logic b; 
} 
} my_signals_list 
  

解决方案

简单的答案：no。

如果你想要这样分组的信号，那为什么不为输入组创建一个结构体和一个输出组的结构？

  typedef struct {
 logic a; 
} input_group_s; 
 
 typedef struct {
 logic b; 
} output_group_s; 
 
 typedef struct {
 input_group_s input_group; 
 output_group_s output_group; 
} my_signals_list; 
  

正如Greg在注释中指出的那样，您还可以在主结构体内部嵌套struct定义： / p>

  typedef struct {
 struct {logical a; } input_group; 
 struct {logical b; } output_group; 
} my_signals_list; 
  

如果你想以一种很好的封装方式为模块指定信号，我建议使用界面。

Can I have groups inside a struct?

pseudo-code:

typedef struct {
     input_group {
             logic a;
     }
     output_group {
             logic b;
     }
} my_signals_list

解决方案

Short answer: no.

If you want to have signals grouped like this, why not create a struct for the input group and a struct for your output group?

typedef struct {
  logic a;
} input_group_s;

typedef struct {
  logic b;
} output_group_s;

typedef struct {
  input_group_s input_group;
  output_group_s output_group;
} my_signals_list;

As Greg points out in the comments, you can also have nested struct definitions inside the main struct:

typedef struct {
  struct { logic a; } input_group;
  struct { logic b; } output_group;
} my_signals_list;

If you want to specify signals for a module in a nice encapsulated fashion, I would suggest using an interface, though.
