4 To 16 Decoder Using 2 To 4 Decoder Verilog Code

Decoder is a digital circuit that can select a line according to the input pattern. Decoder can be used as a control unit for a MCU,processor etc. 4 to 16 line decoder verilog code arr given bellow.

2-to-4 Line Decoder Dataflow Verilog // 2-to-4 Line Decoder with Enable: Dataflow Verilog Desc. // (See Figure 4-10 for logic diagram).

module decoder(x,y,z,w,e,d);
input w,x,y,z,e;
output [15:0]d;
assign d[0]= (~x) & (~y) &(~z) & (~w) & (e) ;
assign d[1]= (~x) & (~y) &(~z) & & (e) ;
assign d[2]= (~x) & (~y) &(z) & (~w) & (e) ;
