You can check 16 to 4 encoder using 8 to 3. Verilog implementation is simple. Therefore provided that the three Enable inputs E1 E2 and E3 of the decoder are fed with the appropriate logic levels to enable the decoder each of the Y0 to Y7 pins of the decoder will output a logic 0 for one of the 8 possible combinations of the three bit value on the address lines A 13 to A 15Since this three bit value will only change when the 16-bit value on the address bus changes by 8192 10 2000 16 the memory chips will be selected using their chip select CS inputs every 8. 4Half of 16 is 8. Check also: using and 16 to 4 encoder using 8 to 3 In 8 to 3 line encoder there is a total of eight inputs ie Y 0 Y 1 Y 2 Y 3 Y 4 Y 5 Y 6 and Y 7 and three outputs ie A 0 A1 and A 2.
Assign A0 Y3 Y2. As always we start with the module and port declarations.

Assign A1 Y3 Y2.
Hence we get 16 outputs using 4 common inputsThis is the princple of designing a 4 to 16 decoder using two 3 to 8 decoders. For the other eight input states the and is true so the NAND puts out a low. Hence our final code. The output ay be configured as either active high or active low levels input and output and are 335 volt logic levels. If none of the inputs to the upper encoder are asserted then the outputs of the lower encoder become the overall outputs and Y2 needs to be negated. Now we have to describe the flow of data to the outputs using assign.
