The always keyword acts similar to the “C” construct while(1) {..} in the sense that it will execute forever. The other interesting exception is the use of the initial keyword with the addition of the forever keyword. The example below is functionally identical to the always example above...

44. Explain parameter overriding in Verilog. In Verilog, when you make something using a template (like a module), you can set certain values that can be changed later when you actually use that thing in your project. This changing of values is called “parameter overriding.” It’s like ...
The $attribute keyword looks like a system task invocation. The difference here is that the parameters are more restricted than those of a system task. The <identifier> must be an identifier. This will be the item to get an attribute. The <key> and <value> are strings, not expressions,...

Parameters must be defined within module boundaries using the keyword parameter. A parameter is a constant that is local to a module that can optionally be redefined on an instance-byinstance basis. For parameterized modules, one or more parameter declarations typically precede the port declarations ...
