Floating-Point Convertor

Using a hardware design made with System Verilog to convert a 32-bit float-value into a decimal representation of 5+ digits.

How to Use:

1. First, open the top_level_tb.sv file, and find lines 8 and 21:

2. You can change the amount of DISPLAY_WIDTH, and the binary floating point number for the module to convert like so:

3. Then build the project in ModelSim, use top_level_tb as the design.

4. Finally, run the simulation. It will create an output file containing the converted floating point value in the desired number of digits!
