5~6年工作經驗
職責要求
•Design high-speed TX/RX analog buffer circuits for LPDDR6 memory interfaces, including output drivers, input receivers, level shifters, termination, impedance calibration, biasing, and reference circuits.
•Define and implement programmable drive strength, slew-rate control, and on-die termination schemes to meet LPDDR6 electrical and timing requirements.
•Translate system and interface specifications into detailed transistor-level circuit architectures and design specifications.
•Own end-to-end block/IP delivery, including architecture studies, schematic design, pre-layout simulation, post-layout extraction, and sign-off.
•Build and maintain verification test benches; validate performance across PVT corners, mismatch/Monte Carlo, aging, and post-extraction parasitics.
•Analyze high-speed performance metrics such as eye margin, jitter, timing skew, voltage noise sensitivity, and simultaneous switching effects.
•Work closely with layout engineers to provide floorplanning guidance, review critical layouts, and ensure robust matching, isolation, and parasitic control.
•Support interface integration and sign-off, including power, performance, area (PPA) optimization and reliability checks (e.g., EM/IR, overstress, aging).
•Support testchip and product silicon bring-up, characterization, and correlation with simulation results; drive root-cause analysis and ECOs as needed.
•Collaborate effectively with digital design, verification, layout, package, SI/PI, product, and test teams.
任職資格
•BS or MS in Electrical/Electronics Engineering or related field.
•Typically 5+ years of relevant experience in analog/mixed-signal IC design, with emphasis on high-speed I/O or memory interface circuits.
•Strong fundamentals in CMOS device operation, analog circuit design, feedback and stability, noise/jitter analysis, and deep-submicron effects.
•Hands-on experience designing high-speed TX/RX buffers, termination and impedance calibration circuits, and voltage-domain level shifters.
•Proficiency with industry-standard design tools, typically including Cadence Virtuoso, Spectre/ADE or HSPICE, and post-layout extraction flows.
•Ability to clearly communicate design intent, document trade-offs, and drive results in a cross-functional environment.
•Basic written English proficiency required. Candidates must be able to read and write emails in simple English to communicate effectively with non-Mandarin-speaking colleagues.
Preferred / Nice-to-Have Experience
•Experience with memory or high-speed interface protocols such as LPDDR, DDR, HBM, or similar interfaces.
•Experience with post-layout sign-off, EM/IR analysis, and reliability-aware analog design.
•Familiarity with signal integrity concepts, channel effects, and interaction between I/O circuits and package/channel parasitics.
•Experience supporting silicon validation, ATE characterization, and simulation-to-silicon correlation.
•Scripting or automation experience using Python, SKILL, Verilog-A, or similar for simulation regression and result analysis.
