Flip-flops are extremely simple electronic circuits, forming the basis of clock circuits, memory circuits, buffers, and shift registers. Through his dilly-dallying with digital logic, [Jeffrey] decided he would build his own. Not with Verilog or VHDL, though, but Migen: the Python-based way to build digital circuits with software.

Migen is an interesting tool that makes traditional FPGA programming a lot easier; instead of Verilog or VHDL, Migen allows an FPGA to be programmed in Python. Yes, it’s the tool you’ve been waiting for, and the tutorials make it look pretty easy. After installing Migen, [Jeff] wrote a class for a D flip-flop in only three lines of code. That’s three readable lines of code, and he was able to simulate the flip-flop with gtkwave in another two lines. Compared to learning the complexities of VHDL or Verilog, Migen makes digital logic and FPGA programming a breeze.

[Jeff] has a great tutorial for building a D flip-flop with Migen, but we’d love to see some more complex examples of what can be done with this very cool tool. If you’re building (or have built) something with Migen, be sure to send it in and relate your experiences.
