Hexadecimal-to-Octal Converter with Display Input: 1-digit Hexadecimal Number represented by 16 input points Output: 2-digit Octal Number represented by 8 output points Logic Function The circuit will convert the hexadecimal input into its octal equivalent. Both the input and output must be displayed using a seven-segment display.

Hexadecimal to Seven segment
The hexadecimal to seven segment encoder has 4 bit input and 7 output. Depending upon the input number, some of the 7 segments are displayed. The seven segments are represented as a, b, c, d, e, f, g. A high on one of these segments make it display.
A combinational circuit that converts a hexadecimal digit to an appropriate code for the selection of segments in an indicator used to display the decimal digit in a familiar form. The seven outputs of the decoder select the corresponding LEDs in the display, as shown in figure below .
Truth Table
The truth table for this display is given below:
The K Map for a is given below:
The K Map for b is given below:
The K Map for c is given below:
The K Map for d is given below:
The K Map for e is given below:
The K Map for f is given below:
The K Map for g is given below:
Therefore these are the detail information related to hexadecimal to 7 segment series with k map of each (a, b, c, d, e, f, g).

We will be moving on to write slightly more complex example, this time a hex to seven segment encoder. Basically LED number is displayed with 7 segments.
The hexadecimal to 7 segment encoder has 4 bit input and 7 output. Depending upon the input number, some of the 7 segments are displayed. The seven segments are represented as a,b,c,d,e,f,g. A high on one of these segements make it display. For example to write 1 we need to display segments b and C.
The 7 segment display also has a decimal point dp. The figure below explains this Let write this example making use of the verilog case statement
7 Segment Display Common Anode Hex Code
Note that we had to assign out as a register in
reg out; In our case, it was not required because we had only one statement. We now suggest that you write a test bench for this code and verify that it works. If you have sifficulty, you can check it with following test bench

1. Change the above hex to BCD verilog code so that it take negative logic. A segment is on when it gets 0. A segment is off when it gets logic 1.
