there are a number of circuits that are difficult to flatten, because the number of terms created is extremely large An equation that only contains AND functions produces one term A function that contains a large XOR function can produce hundreds or even thousands of terms A 2-input XOR has the terms A and (not B) or B and (not A) An N-input XOR has 2**(N-1) terms For instance, a 16-input XOR has 32,768 terms and a 32bit XOR has over 2 billion terms Clearly, designs with these types of functions cannot be flattened Flattening gets rid of all of the implied structure of design whether it is good or not Flattening works best with small pieces of random control logic that the designer wants to minimize Used in conjunction with structuring, a minimal logic description can be generated Usually, the designer wants a design that is nearly as fast as the flattened design, but is much smaller in area To reduce the fanout of the input pins, terms are shared Some synthesis vendors call this process structuring or factoring

Factoring is the process of adding intermediate terms to add structure to a description It is the opposite of the flattening process Factoring is usually desirable because, as was mentioned in the last section, flattened designs are usually very big and may be slower than a factored design because of the amount of fanouts generated Following is a design before factoring:

Factoring usually produces a better design but can be very designdependent Adding structure adds levels of logic between the inputs and outputs Adding levels of logic adds more delay The net result is a smaller design, but a slower design Typically, the designer wants a design that is nearly as fast as the flattened design if it was driven by large drivers, but as small as the completely factored design The ideal case is one in which

the critical path was flattened for speed and the rest of the design was factored for small area and low fanout After the design has been optimized at the boolean level, it can be mapped to the gate functions in a technology library

Mapping to Gates
The mapping process takes the logically optimized boolean description created by the optimization step and uses the logical and timing information from a technology library to build a netlist This netlist is targeted to the user s needs for area and speed There are a number of possible netlists that are functionally the same but vary widely in speed and area Some netlists are very fast but take a lot of library cells to implement, and others take a small number of library cells to implement but are very slow To illustrate this point, let s look at a couple of netlists that implement the same functionality Following is the VHDL description:
LIBRARY IEEE; USE IEEEstd_logic_1164ALL; USE IEEEstd_logic_unsignedALL; ENTITY adder IS PORT( a,b : IN std_logic_vector(7 DOWNTO 0); PORT( c : OUT std_logic_vector(7 DOWNTO 0) PORT( ); END adder; ARCHITECTURE test OF adder IS BEGIN c <= a + b; END test;
Both of the examples implement an 8-bit adder, but the first implementation is a small but slower design, and the second is a bigger but fast design The small but slower design is an 8-bit ripple carry adder shown in Figure 9-9 The bigger but faster design is an 8-bit lookahead adder shown in Figure 9-10 Both of these netlists implement the same function, an 8-bit adder The ripple carry adder takes less cells to implement but is a slower design because it has more logic levels The lookahead adder takes more cells to implement but is a faster design because more of the boolean operations are calculated in parallel The additional logic to calculate the functionality in parallel adds extra logic to the design making the design bigger
