Learn MYHDL with Real Code Examples

Install Python 3.x on your development machine

Install MyHDL via pip: `pip install myhdl`

Optionally install a VHDL/Verilog simulator (GHDL, Icarus Verilog)

Set up your preferred Python IDE or editor

Run example MyHDL scripts to validate installation

Install Python 3.x

Install MyHDL library via pip

Install VHDL/Verilog simulator (optional)

Set up waveform viewer (GTKWave)

Verify examples to ensure environment works

Python source files for hardware modules

Testbench scripts

Conversion scripts to HDL

Waveform output or log files

Optional simulator configuration files (GHDL/Icarus)

python my_design.py - Run simulation

myhdl.toVerilog(module, args) - Convert to Verilog

myhdl.toVHDL(module, args) - Convert to VHDL

ghdl -r top - Run GHDL simulation

iverilog -o out.vvp top.v - Run Verilog simulation with Icarus

Python code language-independent

Documentation in multiple languages

Standard HDL output compatible worldwide

Python libraries support Unicode

Community examples often multilingual

Accessible through Python IDE or command-line

Simulation and conversion workflows cross-platform

Testbenches fully Python-scripted

Waveforms viewable with open-source tools

Documentation and tutorials freely available online

Minimal UI; uses waveform viewers like GTKWave

Simulation outputs printed in console

Optional Python plotting via matplotlib for results

IDE-dependent visualization (PyCharm, VSCode, etc.)

No hardware GUI unless deployed to FPGA

Signals track hardware state

Process decorators define updates on clock or event edges

Testbenches manage stimulus and expected outputs

Simulation maintains internal event queue

Conversion preserves hardware semantics for HDL

Use Python variables and lists to generate test data

Store simulation results in files or waveform traces

Large test datasets managed efficiently via Python structures

Use assertions to validate expected outputs

Optional export for automated verification pipelines
