Interface Protocols for Silicon

AMBA, coherent fabrics, memory interfaces, PCIe/CXL, embedded serial buses, high-speed I/O, and protocol verification for silicon teams.

Course promise

This is the protocol course for chip engineers. It teaches how to read protocol behavior from waveforms, logs, counters, VIP failures, firmware setup, and silicon symptoms.

  • Protocol fundamentals before protocol names.

  • AMBA, coherence, memory, PCIe/CXL, peripherals, and high-speed I/O.

  • Verification, compliance, debug, and interview practice.

  • Every topic follows metric -> layer -> contract -> artifact -> fix.

Metrics and artifacts to collect

  • latency

  • throughput

  • error rate

  • compliance status

Mini case study

Always anchor debug to the first bad transaction.

Debug branches

  • Name layer

  • Name ID

  • Name artifact

Senior review question

Ask: what is the first transaction that deviates, and which spec rule does it test?
