How to run

Just run makeor follow the steps:

1. Analyze the source file(s):

   ghdl –a --ieee=synopsys <design>.vhd
   

2. Analyze the testbench file(s):

   ghdl –a --ieee=synopsys tb_<design>.vhd
   

3. Generate executable file:

   ghdl –e --ieee=synopsys tb_<design>
   

4. Run the simulation:

   ghdl –r --ieee=synopsys tb_<design> --vcd=tb_<design>.vcd
   

5. View the waveform:

   gtkwave tb_<design>.vcd
