AIM:
To implement Encoder 8 To 3 in Dataflow Modelling using verilog and validating their functionality using their functional tables
SOFTWARE REQUIRED: Quartus prime
THEORY
Encoder 8 To 3
The 8 to 3 line Encoder is also known as Octal to Binary Encoder. In 8 to 3 line encoder, there is a total of eight inputs, i.e., D0, D1, D2, D3, D4, D5, D6, and D7 and three outputs, i.e., A0, A1, and A2. In 8-input lines, one input-line is set to true at a time to get the respective binary code in the output side. Below are the block diagram and the truth table of the 8 to 3 line encoder.

Truth Table
The logical expression of the term A0, A1, and A2 are as follows:
A0 = D1 + D3 + D5 + D7
A1 = D2 + D3 + D6 + D7
A2 = D4 + D5 + D6 + D7
Logical circuit of the above expressions is given below:
