As a CPU Design Timing Engineer at Apple, you will play a critical role in ensuring timing closure for CPU projects. You will collaborate with various teams, including CAD, micro-architects, and implementation engineers, to develop and refine timing flows. Your expertise will help drive the timing analysis and closure processes, contributing to the development of groundbreaking Apple products. This position requires a deep understanding of timing analysis and the ability to work with complex digital designs.

• Minimum BS degree and 10+ years of relevant experience
• Experience with a static timing analysis tool such as PrimeTime or Tempus
• Experience with timing analysis involving multiple clock and power domains
• Experience with variation modeling
• Experience with TCL and either Perl or Python
• Experience with SDC command usage including clock definitions and timing exceptions
• Prior experience performing timing analysis in high-speed digital designs such as CPUs
• Understanding of physical design tools and methodology
• Understanding of deep sub-micron technologies and scaling trends
• Working knowledge of CPU microarchitecture and timing paths
• Working knowledge of clock-domain crossing and reset-domain crossing
• Experience with RTL modeling and assertion-based verification is a plus
• Possess data parsing, analysis, and representation skills

• Work with the CAD team to develop the timing flow for the project.
• Script to improve analysis flows and engineer efficiency.
• Collaborate extensively with CPU micro-architects and implementation engineers.
• Drive timing closure for the CPU.
• Perform timing analysis and address any issues that arise.
