Not with Verilog or VHDL, though, but Migen: the Python-based way to build digital circuits with software. [Jeff] has a great tutorial for building a D flip-flop with Migen, but we’d love to see ...

In this module use of the VHDL language to perform logic design is explored further. Many examples of combinatorial and synchronous logic circuits are presented and explained, including flip-flops, ...
