Part 1 · Logic and state
Combinational and sequential intent
Start by locating storage. Then make assignment coverage, clocking, reset, width, and priority explicit.

Part 1 · Logic and state
Finite-state machines as timing contracts
Define legal states, sampled transition conditions, outputs, priority, and recovery before choosing an encoding.
Part 2 · Clock boundaries and flow
CDC and reset strategy selection
Choose a crossing structure from signal semantics, event rate, coherency, latency, and loss tolerance.
Part 2 · Clock boundaries and flow
Ready-valid, backpressure, and FIFO boundaries
A correct interface preserves payload, ordering, and occupancy through stalls and simultaneous events.
Part 3 · Synthesis and proof
Synthesis, timing, and proof
Finish every answer by naming the inferred hardware, implementation pressure, corner cases, and evidence.
