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.

Verilog Code for 2 to 4 Decoder Behavioral Modelling using Case Statement with Testbench Code. Module 24DEC( input 1:0din, output 3:0dout ); reg 3:0dout. For each case the decoder should output a 16-bit digit with only one of the bits high. I can't manage to get all the desired outputs when I run the program.
