The CPU Processor Performance Verification Engineer will play a crucial role in chip design at Apple, focusing on silicon performance verification, correlation, characterization, and tuning for CPUs. This position involves collaboration with architects, RTL designers, and software developers to identify and resolve performance bottlenecks. The engineer will develop test plans and tools for performance tuning and verification, ensuring that performance features are accurately verified. The role requires strong communication skills to present performance results to multi-functional teams.

• Bachelor's degree in a relevant field.
• Academic experience with performance modeling, processor verification, or RTL design.
• Academic experience in digital logic design, CPU architecture, and microarchitecture.
• Experience in at least one of the following: assembly, C/C++, Verilog, or System Verilog.
• Experience in developing performance test plans and writing/debugging assembly tests for performance correlation and verification.
• Experience in benchmark and workload analysis and CPU performance profiling.
• Knowledge of compiler techniques and OS for performance optimization.
• Knowledge in developing instruction profiling tools on silicon.
• Experience in performance modeling for advanced CPU designs.
• Experience in silicon validation.
• Ability to work across teams to optimize silicon performance.
• Excellent communication and presentation skills.

• Work closely with architects and RTL designers on verifying the performance features of the design and correlating with performance models.
• Collaborate with software and application developers on identifying performance bottlenecks and tuning the software.
• Develop test plans and test infrastructure/tools for performance tuning, correlation, and verification.
• Improve and maintain the architectural performance models.
• Develop tests in assembly, C/C++, or vectors to debug and correlate the RTL and performance model.
• Create C or Verilog-based checkers for verifying the performance features.
• Develop coverage monitors and analyze coverage to ensure all performance features are covered.
• Debug performance issues and conduct performance tuning on silicon.
• Benchmark, correlate, and compare CPU performance across silicon/OS/compiler versions.
• Present CPU performance results to multi-functional teams.
• Work closely with OS and compiler teams on system and application performance tuning.
