In this highly visible role, you will be at the center of a chip design effort collaborating with all subject areas, with a critical impact on getting functional products to millions of customers quickly.
You will be responsible for silicon performance verification, correlation, characterization and tuning for CPUs. The role involves pre-silicon performance verification as well as developing tests to characterize CPU performance, analyzing and profiling software/applications, correlating and comparing performance across silicon/system software version, and working with OS and compiler teams on performance debug and tuning.
Key Qualifications
- Minimum BS and 3+ years of relevant industry experience.
- The ideal candidate should have performance modeling, processor verification, or RTL design experience
- In-depth knowledge of digital logic design, CPU architecture and microarchitecture
- Experience in performance modeling for advanced CPU designs
- Experience in developing performance test plans and writing/debugging assembly tests for performance correlation and verification
- Good programming skills in assembly, C/C++, Verilog, System Verilog, and scripting
- Proven experience in benchmarks and workload analysis
- Experience in CPU performance profiling
- Good knowledge in compiler techniques and OS for performance optimization
- Proven knowledge with developing instruction profiling tools on silicon
- Ability to work across teams to optimize silicon performance
- Experience in silicon validation is a plus
- Should be a great teammate with excellent communication and presentation skills and able to work independently on the owned unit
Description
As a Chip Performance Engineer owning the verification of a certain area of performance features in a chip design, you will have responsibilities as follows:
• Work closely with architects and RTL designers on verifying the performance features of the design and correlating with performance models (both pre-silicon and post-silicon)
• Work closely 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
• Develop 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
