There was movement at the (Fremont) station...

Chris has finally started looking at the power supplies - yah!

He has asked me to estimate the core power consumption for the Cyclone V... and of course at this stage I have no idea. So my immediate task is to instantiate enough logic to fill the device and run a power estimator on it... exactly how I'm going to do this is undecided atm, since Quartus will happily optimise out all the unused logic.

One option is to instantiate a bunch of 68K processor cores and hook them up in such a way as to avoid them being optimised out. If nothing else it'll be a fun exercise to see how many I can fit in the device. I'm sure I'll come up with something in the next few days...

EDIT: Apparently I can fit 32x TG68 cores at 82% logic utilisation!
