Further, we can combine these operators to define new operators e.g. ![]() ![]() Here i0 - i3 the input lines, whereas s0 and s1 are the selection line. Base on thé values óf s0 and s1, the input is sent to output line, e.g. Now, we need to change it only at one place i.e. In this wáy, we can rémove the hard Iiterals from the codés. But we cán define the paraméter in the moduIe, which can bé modified during componént instantiation in structuraI modeling style ás shown below. The always bIock (lines 13-19) compares a and b and set the value of z to 1 if these inputs are equal, otherwise set z to 0. Structural modeling is used in Line 9, where parameter mapping and port mapping is performed. Note that, in line 16,.N(5) will override the default value of N i.e. N2 in Listing 3.3. Also, parameter M is not mapped, therefore default value of M will be used, which is defined in Listing 3.3. In this wáy, we can rémove hard literals fróm the codés, which enhances thé reusability of thé designs. Value of the parameter N can also be set using defparam keyword, as shown in Listing 3.5. Further Parameters ánd localparam are shówn which can bé useful in créating the reusable désigns.
