// Generate verilog lines assigning array output from binary final input

//

// Looks like this:

//

// 0 : wb_dat_o <= 32'h18000000;

// 1 : wb_dat_o <= 32'h18200000;

// 2 : wb_dat_o <= 32'h1880b000;

// 3 : wb_dat_o <= 32'ha8400051;

// 4 : wb_dat_o <= 32'hd8041000;

// 5 : wb_dat_o <= 32'h18c00000;

// 6 : wb_dat_o <= 32'h18e00000;

//

// etc...

//

// The generated file is pulled into the appropriate part of a verilog 

// module and gets synthesized.
