This Verilog code implements an 8x3 priority encoder using behavioral modeling. The module takes an 8-bit input and outputs a 3-bit value representing the highest priority bit. The code uses casex ...

Priority Encoder is a combinational digital circuit, that take 2^n input lines and encodes it to n output signal lines. For instance for a 8x3 priority encoder the output lines with respect to 8, i.e.
