When were instance arrays added to Verilog?
Instance arrays were added in Verilog-1995, but many software tools did not support them until Verilog-2001. Multiple instances of a module can also be created using a generate block (see section 9.0). parameter values within a module may be redefined for each instance of the module.

What is a configuration block in Verilog?
The configuration block contains a set of rules for searching for the Verilog source description to bind to a particular instance of the design. design specifies the library and cell of the top-level module or modules in the design hierarchy. There can only be one design statement, but multiple top-level modules can be listed.

How does Verilog re-evaluate a signal?
stems from the use of Verilog for simulation; whenever any signal on the right-hand side changes its state, the value offwill be re-evaluated. The effect is equivalent to using the gate-level primitives in Figure 2.37. Following this approach, the circuit in Figure 2.39 can be speciﬁed as shown in Figure 2.41.

What is a signed Reg variable in Verilog?
Signed reg variables were added in Verilog-2001. [range] (optional) may only be used with reg variables, and is a range from [msb :lsb] (most-significant-bit to least-significant-bit). If no range is specified, then reg variables are 1-bit wide. The msb and lsb must be a literal number, a constant, an expression, or a call to a constant function.

Rule: The goto repetition operator (Boolean[->n]) allows a Boolean expression (and not a sequence) to be repeated in either consecutive or non-consecutive cycles, but the Boolean expression must hold on the last cycle of the expression being repeated. The number of repetitions can be a fixed constant or a fixed range.

In Verilog we design modules, one of which will be identified as our top-level module. Modules usually have named, directional ports (specified as input, output or inout) which are used to communicate with the module. In this example the module’s behavior is specified using Verilog’s built-in Boolean modules: not, buf, and, nand, or, nor, xor,

illustrating the application of many Verilog constructs, giving the reader an opportunity to discover more advanced features of Verilog. Storage elements are introduced in Chapter 5. The use of ﬂip-ﬂops to realize regular structures, such as shift registers and counters, is discussed. Verilog-speciﬁed designs of these structures are included.
