The Graphics Cache Hierarchy Verification Engineer will play a crucial role in the Silicon Technologies group at Apple, focusing on the pre-silicon RTL verification of graphics memory subsystem units. This position requires a deep understanding of micro-architectural details and the ability to work collaboratively with design leads and architects. The engineer will be responsible for ensuring that Apple products can efficiently handle complex tasks. A strong background in computer architecture and verification methodology is essential for success in this role.

• BS degree with a minimum of 3 years of experience in CPU or GPU architecture.
• Experience developing unit or cluster level test environments.
• Strong fundamental software and programming skills.
• Experience with verification languages such as SystemVerilog.
• Experience with HDL simulators and waveform viewers.
• Experience with cache verification and memory subsystem testing is highly desired.
• Understanding of the Graphics Pipeline is a plus.
• Experience defining and executing unit level test plans.
• Experience with common verification methodologies such as UVM.
• Experience defining coverage space, writing coverage, and achieving coverage closure.
• Experience with Perl, Ruby, Shell scripting, and Makefiles.

• Develop verification plans in coordination with design leads and architects.
• Build and maintain portable verification test bench components and environments.
• Generate directed and constrained random tests.
• Run simulations and debug design and environment issues.
• Create functional coverage points, analyze coverage, and improve the test environment to target coverage holes.
• Create automated verification flows for block verification.
• Apply knowledge of hardware description languages (VHDL/Verilog) to verify complex designs.
• Work with other block, memory subsystem, and core level engineers to ensure a seamless verification flow.
