A union can be declared as packed in the same way as a structure. In a packed union, the number of bits of each union member must be the same. This ensures that a packed union will represent its storage with the same number of bits, regardless of member in which a value is stored....
A very common modeling style with Verilog is to place the source code for each module definition in a separate source file. Typically, the file name is the same as the module name. This style, while not a requirement of the Verilog language, is often used, because it helps to develop an...

So let's say we wanted to make a circuit with two SR-Latches (regardless of how nonsensical this circuit is in reality), each with a switch for their "set" operation and a shared reset button. The output of each latch will be an LED. ...
SystemVerilog extends the Verilog language with a powerful interface construct. Interfaces offer a new paradigm for modeling abstraction. The use of interfaces can simplify the task of modeling and verifying large, complex designs. This chapter contains a number of small examples, each one showing sp...
