CAD Engineer – Analog/RF Simulation Flow & Methodology Engineer
Santa Clara Valley (Cupertino), California, United States
Hardware
Do you love building elegant solutions to highly complex challenges? Do you intrinsically see the importance in every detail? As part of our Silicon Technologies group, you’ll help design and manufacture our next-generation, high-performance, power-efficient processor, system-on-chip (SoC). You’ll ensure Apple products and services can seamlessly and efficiently handle the tasks that make them beloved by millions! Joining this group means you’ll be responsible for crafting and building the technology that fuels Apple’s devices. Together, we will enable our customers to do all the things they love with their devices!
As a member of our CAD team, you will architect, develop, maintain and enhance simulation methodology and solutions for our Analog, RF and mixed-signal designs.
The role requires working with different technology nodes and provide flows/methodologies for the different tool sets. Working in a small CAD team, you will be collaborating with the analog, mixed-signal, and RF circuit design teams. The role will also involve partnering with layout design, technology, and 3rd party EDA tool vendors to drive and coordinate effort of developing and validating simulation flows, enhancing custom design environment, validating checks and doing results analysis.
Key Qualifications
- Strong expertise in circuit simulations with Analog/RFIC design and/or related CAD/automation support areas involving various technology nodes and tape out.
- Expertise with Cadence ADE environment including knowledge of Schematic Editor, PDK, CDF, Callbacks, Netlisting, Analog Design Environment (ADE-L/XL/GXL/Maestro), OCEAN.
- Proficient in Spice simulators, including Spectre, Spectre RF, AFS (BDA), Hspice, ADS, GoldenGate, AMS Designer, XA, Hsim, and FineSim.
- Strong ability to solve simulation accuracy, speed and capacity issues. Knowledge of AC, DC, Tran, Harmonic Balance, S-parameters, Periodic noise, PSS simulations.
- Expertise in device level SOA checks, ERC asserts, statistical simulations using Monte Carlo, PVT and Reliability/aging analysis involving Self-Heating is a plus.
- Experience in evaluating simulation and environment related CAD tool/product applications and driving EDA vendors to meet design requirements.
- Understand custom IC designs, and knowledge of Post-layout DSPF/SPF extraction. Knowledge of behavioral RTL/AMS circuits, experience in Verilog- A/AMS. Knowledge of PDK and spice models qualification.
- Efficient programming skills in SKILL language, Python, Perl, TCL, or Shell. Ability to provide automations for rapid and dynamic design needs. Knowledge in Perforce and/or regressions is preferred.
- Good written and verbal communication skills, and the ability to collaborate well with multi-functional teams and external vendors.
Description
We are a small CAD team, so you will have an impact with the analog, mixed-signal, and RF circuit design teams by:
- Solving issues related to transistor level simulations on Analog, RF and Microwave applications with Spice simulators on command-line and Cadence environment.
- Guide and assist designers in solving tool issues related to ADE, ADE-XL, Maestro and OCEAN and develop automation flows.
- Steer Methodology on SPICE simulation and modeling techniques related to circuits, thereby influencing the advancement of a variety of technology nodes.
- Architect and develop next generation in-house EDA CAD flow solutions related to Analog and Mixed-signal simulations.
