Summary

This blog post demonstrates how to use GHDL for interactive VHDL simulation on Linux, covering installation, basic workflow, and practical tips for everyday use. The author shows how the free open-source simulator can replace proprietary tools for writing and debugging VHDL testbenches and viewing waveforms.

Key Takeaways

• Install and configure GHDL on common Linux distributions and verify a working simulation environment.
• Run the analyze/elaborate/run workflow (ghdl -a, -e, -r) to execute VHDL testbenches interactively.
• Integrate GHDL with waveform viewers like GTKWave and produce VCD/GHW traces for debugging.
• Debug VHDL designs interactively by stepping through testbench outputs, using assertions, and inspecting signals.
• Automate simulations with simple Makefiles and scripts to streamline iterative development.
