Error (10161): Verilog HDL error at traffic.v(47): object "tempa" is not declared提示信号tempa 没有声明(定义)。一般情况下 在always 里产生的信号,都应该用reg 进行声明 相关知识点: 试题来源: 解析 在模块内声明`reg tempa;` 错误提示表明"tempa"未声明。在Verilog HDL中

The <key> and <value> are strings, not expressions, that give the key and the value of the attribute to be attached to the identified object.Attributes are [<key> <value>] pairs and are used to communicate with the various processing steps. See the documentation for the processing step ...
11,One of the key features of object-oriented programming is the ability to create new classes that are based on existing classes. A derived class by default inherits the properties and methods of its parent or base class. However, the derived class may add new properties and methods, or mo...
typedef keyword, as discussed in section 4.1 on page 75. Declaring a structure as a user-defined type does not allocate any storage. Before values can be stored in the members of a structure that is defined as a user-defined type, a variable of that user-defined type must be declared. ...
It is illegal to declare another object with the same name as the function in the scope where the function is declared. Inside a function, there is an implied variable with the name of the function, which may be used in expressions within the function. It is, therefore, also illegal to ...
Now that we have defined a hierarchy, we can reference any named Verilog object or hierarchical name reference, by concatenating the names of the modules, module instance names, generate blocks, tasks, functions, or named blocks that contain it. Each of the names in the hierarchy is separated...
objects. Modules are instantiated inside other modules, and each instantiation is creating a single object from that template. The exception is the top-level module which is its own instantiation. The modules ports must to be matched to those which are defined in the template. It is specified ...
4.4 指向Member Function的指针 (Pointer-to-Member Functions) 取一个nonstatic data member的地址,得到的结果是该member在 class 布局中的byte位置(再加1),它是一个不完整的值,须要被绑定于某个 class object的地址上,才可以被存取. 取一个nonstatic member function function 方法 c/c++ 3d 多重继承 编译...
module mod_name(i_port, ...) input name_of_struct i_port; Quartus II just dumps out a bunch of errors saying "Verilog HDL error: object "name_of_struct" is not declared. It's like QuartusII isn't actually seeing my `include file or something. Any suggestions? The console win...
