module parameters can be modified at compilation time to have values that are different from those specified in the declaration assignment. This allows customization of module instances. A parameter can be modified with the defparam statement or in the module instance statement. Typical uses...

A module consists of a port declaration and verilog code to implement the desired functionality Modules should be created in a verilog file where the filename matches the module name(the module below should be stored in full_adder.v)
2. Syntax and Declaration Parameters are declared using the `parameter` keyword in Verilog. They can be declared at themodule, generate block, or local scope level. The general syntax for declaring parameters is as follows: parameter <type> <name> = <value>; Here, `<type>` represents the...
The module shown below uses parameters to specify the bus width, data width and the depth of FIFO within the design, and can be overriden with new values when the module is instantiated or by usingdefparamstatements. // Verilog 1995 style port declarationmoduledesign_ip(addr,wdata,write,sel,...

Hrm, I found a copy of the Verilog 2001 spec, and it mentions this in section 3.11.1 Module parameters: A parameter declaration with no type or range specification shall default to the type and range of the final value assigned to the parameter, after any value overrides have been applied...
