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.

Key Qualifications

  • In-depth knowledge of digital logic design, CPU and SOC architecture/micro-architecture and memory subsystem
  • Strong programming (C/C++, Verilog, Scripting), software optimization, and performance improvement skills
  • Experience in unit and full chip level test benches
  • Experience in developing testplans, assertions, and developing stimulus
  • Should be a team player with excellent communication skills and be able to work independently on the verification efforts for a block/area of the design
  • Experience with emulation and developing synthesizable transactors is a plus


• Play a critical role in end-to-end verification of memory subsystem by developing an in-depth understanding of cache coherence protocols and functioning of various units in CPU/GPU/SOC that are relevant to memory subsystem verification. These units include Load-Store unit, different levels of caches, bus interface units, memory controller, etc. • Develop verification environment which can be used in both simulation and emulation • Develop synthesizable transactors and test benches and support verification hooks for verifying memory subsystem functionality and CPU/SOC features • Develop unit level stimulus as well as full chip assembly programs to verify memory subsystem • Develop verification IPs that can be utilized by Apple teams worldwide • Work closely with CPU/SOC/GPU RTL design teams and understand the specification in detail for developing verification strategy for the above mentioned environment taking system level considerations into account • Develop coverage monitors and accomplish coverage goals • Debug failures in both pre and post silicon environments, root-cause problems, and propose design changes to address issues • Develop abstract end-to-end checks to verify CPU-SOC memory subsystem interaction and coherence protocols • Use novel techniques such as formal verification, emulation/FPGA technology, as well as industry standard tools and languages to verify memory subsystem
