Responsibilities

• Play a meaningful 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 shown 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

Minimum Qualifications

• BS, MS, or Ph.D. in Computer/Electrical Engineering is required.

Preferred Qualifications

• The ideal candidate should have 2+ years of processor verification experience.
• In-depth knowledge of digital logic design, CPU and SOC architecture/micro-architecture and memory subsystem
