VHDL-Lab

A repository for VHDL codes for the Computer Architecture Course

🧨How To Run VHDL Codes

1. Install the GHDL Compiler

2. Add Path for GHDL in environment variables (for windows)

3. Install GTKWave for showing wavelength

4. use the following GHDL commands to synthesize and run your simulation

GHDL-Commands

use -s for non-testbench .vhd files

use -a for all .vhd files including

use -e for testbench file

use -r for testbench file followed by --vcd=out.vcd

check below for example:

🎇checks syntax

ghdl -s [filename].vhd

🎇analyzes file

ghdl -a [filename].vhd

🎆analyzes TestBench

ghdl -a [filename_tb].vhd

🎆evaluates TestBench

ghdl -e [filename_tb]

🎆runs TestBench

ghdl -r [filename_tb] --vcd=out.vcd

🎈Open vcd file in GTKWAVE

gtkwave out.vcd
