IGNITION MODULE

The IGNITION MODULE is designed to fire the spark plugs on a V6 or V8 engine. As such it is a somewhat unusual puzzle, requiring all 8 outputs to be active most of the time. Don't worry if you're not a gearhead, it's just to give this puzzle some context, you don't need any car knowledge to solve this puzzle. You are afforded a generous amount of board space to handle not just the number of outputs but also two completely different output patterns.

• ignition is a simple input indicating with a pulse when to fire the next spark plug.
  
• cylinder 1 through cylinder 8 are simple outputs connected to their corresponding cylinder's ignition coil.
  To fire a spark plug interrupt power to its coil.
  
• cylinders is a dial allowing configuration of the module for either 6 or 8 cylinders.
  Each configuration has its own specific firing order:
  6 cylinders: 1-4-2-5-3-6
  8 cylinders: 1-5-4-8-6-3-7-2

To solve this puzzle you'll need to find a way to translate the firing orders to code, while also managing to fit all your components and connections on the board. Or perhaps the board is really plenty large once you find a really ingenious solution - I haven't, but the clever solutions players come up with never cease to amaze me!

For those wanting to know why the outputs have to be high all the time and pulsed low to generate a spark, have a look at Ignition coil on Wikipedia[en.wikipedia.org].
