CAD Engineer – Timing for Transistor-Level Flows & Methodologies

Austin, Texas, United States


Role Number:200116299
Do you love creating 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, you and your team will enable our customers to do all the things they love with their devices. In this role you will own defining, implementing, and supporting the methodologies, flows, and tools necessary to verify transistor-level circuits in the areas of timing, signal integrity and circuit verification. You will work very closely with digital and analog designers to ensure that their designs meet functionality, timing, electrical, power, and signal integrity goals.

Key Qualifications

  • Typically requires at least 3+ years of hands on experience in timing, STA, CAD/methodology, etc
  • Proficiency in STA and relevant methodologies for timing closure, signal integrity analysis, cross-talk, and OCV (AOCV, POCV) effects, etc
  • Proficiency in formal/functional/logic-to-circuit equivalence checking (FEC) techniques and implementation a plus
  • Experience with transistor-level tools such as NanoTime, PathMill, ESP (Verilog to Spice equivalence checking), LEC, HSPICE
  • Familiar with digital custom circuit designs including dynamic circuit techniques and memories as well as SPICE models and netlists
  • Experience programming in Perl, TCL, or similar language
  • Strong communicator who can accurately describe issues and follow them through to completion


In this exciting role, you will: - Collaborate with design teams to understand and debug tool issues and constraints - Build/maintain flows, scripts and methodologies for transistor level analysis - Work closely with both the Design and CAD teams to drive timing, power, signal integrity, and functional verification closure efforts - Perform deep analysis of timing paths to identify key issues - Document and help build guidelines/specs
