Summary

Role - DDR Engineer
Location - San Jose CA
Key skills: Zebu, FPGA, DR (All generations), ARM, DDR PHY, logic analysers, oscilloscopes, and simulation waveforms
Job Description 
  • Ensuring DDR PHY and controller designs adhere strictly to JEDEC standards (DDR4/DDR5/LPDDR5/LPDDR6)
  • Using simulators (e.g., VCS) and emulators (e.g., Synopsys ZeBu, Cadence Palladium) to debug design failures and root cause issues before tape-out.
  • Validating power-sensitive LPDDR5 states, including self-refresh and deep power-down modes.
  • Running simulations to verify timing margins, memory throughput, and latency, often collaborating on Python scripting for automation.
  • Ensuring proper integration between the DDR controller, PHY, and SoC firmware
  • Develop and execute test plans in C to validate the Features.
  • In-depth knowledge of one or more peripheral protocols and specifications
  • Bare metal/Linux driver development, Firmware development.
  • Understanding Pre-Silicon Validation for DDR4/LPDDR4/LPDDR5
  • Pre-silicon validation means verifying design and firmware before the silicon chip is fabricated. It includes simulations, emulation, and formal verification to catch bugs early.
  • For DDR memory interfaces (DDR4, LPDDR4, LPDDR5), pre-silicon validation focuses on:
  • Protocol compliance (timing, command sequences, training sequences)
  • Signal integrity modelling and timing margins
  • Firmware interactions (training firmware, calibration sequences)
  • Power management features (especially for LPDDR5 with deeper power states)
  • Using hardware description languages (HDL) and simulators (like Synopsys VCS, Cadence Incisive) for DDR PHY and controller
  • Proficient in C for low-level firmware
  • Ensuring DDR commands follow JEDEC standards (DDR4/LPDDR4/LPDDR5 specs)
  • Debugging skills using logic analysers, oscilloscopes, and simulation waveforms
  • Good knowledge of memory controller registers and MMIO access.
