Study path

Arm-style ASIC interview preparation

Practice CPU ordering, cache coherence, protocol state, CDC, reset, and low-power boundaries as one connected system. Keep architectural guarantees separate from implementation choices.

Pair each mechanism with assertions, scoreboards, and directed sequences that expose illegal ordering or recovery. These independent exercises do not describe Arm's official interview process.
