A Module is a basic building design block in Verilog and it can be an element that implements necessary functionality. It can also be a collection of lower-level design blocks. As a part of defining a module, it has a module name, port interface, and parameters (optional).

One method of making the connection between the port expressions listed in a module instantiation with the signals inside the parent module is by the ordered list. mydesign is a module instantiated with the name d0 in another module called tb_top.

I want to view a list of all modules/sub-modules/instances in verilog/system-verilog compilation; is that possible? I know i can do a %m in $display and it will show the hierarchy of that particular instance.

A module should be enclosed within module and endmodule keywords. Name of the module should be given right after the module keyword and an optional list of ports may be declared as well. Note that ports declared in the list of port declarations …

Jun 1, 2020 · In this construct, <module_name> would be the name of the module which is being designed. Although we can declare a number of modules in a single file, it is good practise to have one file corresponding to one module. It is also good practise to keep the name of the file and the module the same.

A Verilog module is defined using the keywords module and endmodule. The module name comes after the module keyword, and the ports (input and output) are optionally listed in parentheses. Inside the module, you define its behavior …

Lines 3-5 define the module name and port list, which is the list of inputs and outputs signals. Line 3 gives the port names while lines 4-5 define the port types and directions. Here, all 4 port signals are of type . and are outputs, and and are inputs.

Feb 21, 2016 · In Verilog, a module is declared by the keyword module. A corresponding keyword endmodule must appear at the end of the module definition. Each module must have a module_name, which is the identifier for the module, and a port list, which describes the input and output terminals of the module.

To define a module in Verilog, you use the module keyword, followed by the module's name and a list of its ports. Ports are the interface through which a module communicates with the rest of the design.

The definition of a module begins with the keyword 'module', followed by the module name, a list of ports in parentheses, and then the keyword 'endmodule'. For example: In this case, MyModule is a module with no ports. Ports are the communication interfaces for a module. They allow signals to be passed in and out of the module.
