Usually you start at the verilog level with simulators (I've done this professionally with zero hardware experience and discovered many critical bugs in a chip that's now taped out. Of course the real engineers had to fix them.) Now that it's gone physical, after a series of very low level tests, they will take similar software and adapt it to the interface for hardware instead and repeat all the tests.

Ah makes sense. Thanks for the info, will look into this.

Yes, you can debug on an FPGA first, for example, allowing you to put the hardware-equivalent of a printf statement in places where you need them.

Or, you can configure all of your flipflops into a barrel shift register, so you can read out their contents serially (and shift their contents back in circularly).

But there are many more techniques.

Interesting. Thanks, you've given me a few things to read up on.

How do you propose tapping a line on a piece of silicon with a 14nm feature size?
