Blink LED — Myhdl Code
Toggle an LED using a clocked process in MyHDL.
from myhdl import block, always_seq, Signal, intbv
@block
def BlinkLED(clk, led):
counter = Signal(intbv(0)[24:])
@always_seq(clk.posedge, reset=None)
def logic():
counter.next = counter + 1
led.next = counter[23]
return logicMyhdl Language Guide
MyHDL is a Python-based hardware description language (HDL) that allows designing, simulating, and verifying digital hardware using Python syntax. It enables hardware designers to leverage Python’s flexibility for modeling digital circuits and generating synthesizable VHDL or Verilog code.
Primary Use Cases
- ▸Modeling combinational and sequential logic in Python
- ▸Simulating hardware designs using Python testbenches
- ▸Generating synthesizable VHDL or Verilog code
- ▸Rapid prototyping for FPGA development
- ▸Automated verification of digital designs
Notable Features
- ▸Hardware modeling using Python syntax
- ▸Simulation and testbench integration
- ▸Automatic conversion to VHDL or Verilog
- ▸Support for synchronous and asynchronous logic
- ▸Integration with Python libraries for testing and verification
Origin & Creator
Developed by Jan Decaluwe starting in 2003, MyHDL was created to combine Python’s ease of use with digital hardware design, bridging software and HDL modeling.
Industrial Note
Used in FPGA and ASIC prototyping, hardware verification, digital IP development, and teaching advanced digital design concepts with Python.
