About the job
Own timing closure and develop custom logic for analog/mixed-signal circuits used in Apple products.
What you'll do
- Own custom-design timing closure throughout the project cycle; develop STA constraints and perform block- and chip-level timing and noise analysis.
- Design and characterize transistor- and gate-level custom digital circuits in mixed-signal chips; collaborate on timing changes and design methodologies.
- Support verification and DFT debugging, and assist CAD teams with timing verification and closure flows.
What they ask for
- Bachelor’s degree.
- Solid understanding of timing analysis, including setup/hold calculations, POCV, timing constraints, transistor-level delay characterization, and rise/fall-time balancing.
- Experience with timing analysis and verification in high-speed designs such as SerDes and ADC; in-depth understanding of mixed-signal design techniques.
- Track record delivering silicon IPs with design and verification; proficiency in circuit modeling and simulation, including SPICE models and worst-case corner selection.
Nice to have
- Master’s degree with 3+ years of relevant industry experience; STA tools such as NanoTime, PrimeTime, or Tempus.
- Analog/mixed-signal circuit design, SRAM design, timing/SDC constraints, noise and cross-talk analysis, or scripting in Python, Tcl, or Perl.
Pay
