Скачать или смотреть VHDL 1 - Intro to GHDL and GTKWave

Getting Started with VHDL

The VHDL code and testbench for Blinky is on GitHub.
https://github.com/bustedwing1/ghdl-e...

Install GHDL and GTKWave on Ubuntu 22.04
sudo apt update
sudo apt install ghdl gtkwave

Install GHDL from Source
If you get the following error:
error: unit "numeric_std" not found in library "ieee"
then you can build ghdl from source

sudo apt update
sudo apt install gnat
git clone https://github.com/ghdl/ghdl
cd ghdl
./configure
make
sudo make install

Compile VHDL Blinky RTL and Testbench
There are two steps to compile a VHDL program with GHDL. The first step is to analyze the VHDL source files and the second step is to elaborate, producing the compiled executable.

ghdl -a --std=08 blinky.vhd blinky_tb.vhd
ghdl -e --std=08 tb

Simulate VHDL Blinky with GHDL
The simulation is run with the -r option and the signal waveform is output with the --vcd option. A VCD file is an ASCII text Value Change Dump file captures signal transitions from the simulator.

ghdl -r --std=08 tb --vcd=test.vcd
